I think framed maps would be a great gift for Anthony. Not hearts -- but maybe wrap a square canvas in the map or just get some matching frames with mats -- and get a US atlas at the book store and frame all the places he has lived.
I& got many pins in DIY ARTWORK for repurposing old maps. What a great idea. Pick the image that you like best, stencil or trace it on the piece of paper and cover the map. For example, the Eiffel Tower traced over a map of Paris!
Such a smart idea (feed old book pages through a printer to make unique silhouette art). Not gonna lie, I'd probably scan in the old book pages first, and use the scan for the final print. I love my old books, I don't want to cut them up.
