I recently found a deck of Boeing Earth Day 2013 cards for 50 cents at a Goodwill store near me, but noticed it contains only one Joker. The cards are in immaculate condition, and the tuck case only has some minor wear and tear on the edges. I know it's highly unusual for a deck to have an odd number of cards, so I was wondering - is this deck missing a Joker, or did Boeing only include one, in the name of conservation? Any collectors out there familiar with these cards?
