Scratch-Off World Map
My Scratch Map is covered in gold foil so you can scratch off where you've been.
I normally find the whole idea of showing off where you've traveled on a big wall map to be pretty ostentatious. Hey everybody, look where I've been? Jealous?
But this is pretty inventive. You scratch off the gold foil to reveal the more detailed, colorful map underneath. It's still ostentatious, but I admire the cleverness of the design.
