Mammoth Crossing Pinback Button

A funny yellow diamond warning sign in the style you'd see to advise traffic on the highway. Here the warning is a silhouette of something you don't see every day: a Mammoth! A large elephant-like woolly creature isn't likely to be roaming the highway the next time you go driving, so if you saw this sign you'd look twice for sure! Beware of Woolly Mammoths -- and better look out for Mastadons, too. I hear the sign-makers mix those two mammals up all the time. You can totally customize this gift! Move the sign around, change the background color or style, add your own text or images -- make it your own!
