The question is how well they'll blow up. Even if you buy the large version and scan that, it might still be pixellated or blurry because you're expanding something small into a large frame.
You could buy one of those 1987 calendars with poster size cards, but you only get 12 of them. Some good ones in the mix, though. Lust, one of the Magi, Queen and Two and Six of Disks...And 1987 is same as 2015 so this year you coukd actually use it as a calendar still.
