NewYork inside out pop out map

This version was published just after 9/11 .. I had already moved out of NYC in 1998 and haven’t moved back so I’m not sure how I came to have this. It’s a great little booklet. The pop out map is the best NYC map I’ve ever seen simply because it’s so small and discreet and portable. And the compass makes it super handy because it’s easy to be going uptown only to realize you’ve walked several blocks in the opposite direction. There is a pen in the spine but I can’t figure out how it pops out😂
