Creating Beautiful Bookish Notebook Puns

I sometimes get asked where my ideas come from. The truth is that I often start by drawing something I would like to have. I think antique books are beautiful and I love stationery and I love a clever pun. So my little book pun notebooks were born. Because if you do need a notebook (and let's be honest, don't we all?), why not have a beautiful one that makes you smile every time you see it? What's your favourite bookish pun?
