I would love to see covers reflecting ‘The Time Machine’ by H.G. Wells (public domain), ‘Twenty Thousand Leagues Under The Sea’ by Jules Verne (public domain), ‘Gulliver’s Travels’ by Jonathan Swift (public domain), or ‘Around The World In Eighty Days’ by Jules Verne (public domain). Also, maybe consider adding an elastic band to help keep the book closed (so your passport pages don’t get wrecked). It could be disguised as a bookmark or something. Just a thought from someone who loves her wallet. Best of luck and I can’t wait to see what selections you come up with.
