How to put the title page on the second page?

Question

I know this isn't standard practice, but I need to put the title page of some special document on the back of the first page (i.e on the second page), so the extra white margin appears on the right side instead of the left part. The first page should stay empty. Here's a MWE to try:

\documentclass[letterpaper]{book}
\usepackage[T1]{fontenc}
\usepackage{microtype}
\usepackage{libertine}
\renewcommand*\familydefault{\sfdefault}
\usepackage{anysize}
\marginsize{1.5in}{1in}{0.5in}{0.5in}
\usepackage[x11names]{xcolor}
\definecolor{backgroundcolor}{RGB}{160, 180, 180}
\definecolor{andcolor}{RGB}{230, 255, 255}
\definecolor{subtitle}{RGB}{230, 255, 255}
\usepackage{afterpage}
\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand*{\maintitle}{\begingroup
    \pagecolor{backgroundcolor}
    \centering
    {\fontsize{68}{0}\selectfont{Some Big Title}} \[0.6\baselineskip]
    \vfill
\endgroup}
\begin{document}
\begin{titlepage}
\begin{tikzpicture}[remember picture, overlay]
    \draw[line width = 1in,color = white] ($(current page.north west) + (0.25in,0.25in)$) rectangle ($(current page.south east) + (0.25in,-0.25in)$);
    \draw[line width = 0.25pt,color = black] ($(current page.north west) + (0.75in,-0.25in)$) rectangle ($(current page.south east) + (-0.25in,0.25in)$);
    \draw[line width = 1pt,color = white] ($(current page.north west) + (1in,-0.5in)$) rectangle ($(current page.south east) + (-0.5in,0.5in)$);
\end{tikzpicture}
\maintitle
\LARGE\raggedright
A section\dotfill iii
\vspace*{0.5\baselineskip}
Some comments\dotfill vii
\vspace*{0.5\baselineskip}
One more thing\dotfill ix
\vfill
\end{titlepage}
\end{document}

So what commands should I add to this example to draw the title page on page 2 instead of page 1?

Answer 1

The trick is to insert the empty page inside the environment titlepage like this:

\begin{titlepage}
~\newpage % <===========================================================
\thispagestyle{empty} % <===============================================
\setcounter{page}{1} % <================================================

With the following compilable TeX code

\documentclass[letterpaper]{book}
\usepackage[T1]{fontenc}
\usepackage{microtype}
\usepackage{libertine}
\renewcommand*\familydefault{\sfdefault}
\usepackage{anysize}
\marginsize{1.5in}{1in}{0.5in}{0.5in}
\usepackage[x11names]{xcolor}
\definecolor{backgroundcolor}{RGB}{160, 180, 180}
\definecolor{andcolor}{RGB}{230, 255, 255}
\definecolor{subtitle}{RGB}{230, 255, 255}
\usepackage{afterpage}
\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand*{\maintitle}{\begingroup
    \pagecolor{backgroundcolor}
    \centering
    {\fontsize{68}{0}\selectfont{Some Big Title}} \[0.6\baselineskip]
    \vfill
\endgroup}
\begin{document}
\begin{titlepage}
~\newpage % <===========================================================
\thispagestyle{empty} % <===============================================
\setcounter{page}{1} % <================================================
\begin{tikzpicture}[remember picture, overlay]
    \draw[line width = 1in,color = white] ($(current page.north west) + (0.25in,0.25in)$) rectangle ($(current page.south east) + (0.25in,-0.25in)$);
    \draw[line width = 0.25pt,color = black] ($(current page.north west) + (0.75in,-0.25in)$) rectangle ($(current page.south east) + (-0.25in,0.25in)$);
    \draw[line width = 1pt,color = white] ($(current page.north west) + (1in,-0.5in)$) rectangle ($(current page.south east) + (-0.5in,0.5in)$);
\end{tikzpicture}
\maintitle
\LARGE\raggedright
A section\dotfill iii
\vspace*{0.5\baselineskip}
Some comments\dotfill vii
\vspace*{0.5\baselineskip}
One more thing\dotfill ix
\vfill
\end{titlepage}
\end{document} 

you get the following second (even) page (first (odd) page is empty):

Answer 2

(1) I would just try ...

~ % added
\newpage % added
\begin{titlepage}

The ~ is invisible so that \newpage has something to do :).

Update: Does not work. I guess that the book class always wants to start with an odd page number for that title page. https://zhiganglu.com/post/latex-insert-blank-page/ seems to work but it will change the numbering (\addtocounter{page}{-1}). The OP seems to be a bit angry so I just stop trying to help.

(2) For your next question please understand that you provided way too much code, in my opinion, your problem boils down to:

\documentclass{book}
\begin{document}
~
\newpage
\begin{titlepage}
MY TITL EPAGE
\end{titlepage}
\end{document}

Maybe have a look at this excellent post.
