I've 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!
Placing pictures by a map of where they were taken. Maybe do not as big, smaller maps/pics and put on collage type frame. Or place two small pictures in one frame. Love for wedding/honeymoon/family vacays.
