Sometimes, you have a crazy busy couple of years and your pile of AP cards from misc. sketch card sets tend to pile up because you never have a minute free to actually draw them.
Then, one weekend while you are packing up your house , you are going to get antsy and put all of those cards together in the form of a puzzle... just to prove you can. (Also, because this was a HELL OF A LOT OF FUN TO DRAW AND COLOR).
