Well, someone like me would argue that it should definitely not end-up in the recycle bin

However, it doesn't appear that maps are extremely valuable unless you have some of the very, very early initial years maps.
For your 1976 Disneyland map, you might get anywhere from $5-$20, I'd guess, assuming it's in excellent condition and not like most maps which have been in people's pockets/bags for an entire day.
