GameBoy Cameras....
Man, I remember it was around 1998 when these were in full swing at retailers.
Toys R Us Stores (all of which are now defunct) had display kiosks set up at various places in the store. Other retailers like Target, Circuit City, EB Games and even Funcoland (before all of them were reverted to "GameStop" stores) had display kiosks which contained a GameBoy Pocket, a GameBoy Camera and a GameBoy Printer, with a roll of 'complimentary' stickers which could be printed with images taken through the GameBoy Camera.
Naturally, people were quite inconsiderate and they would vandalize the kiosk by taking pics of their ugly mugs and plastering the kiosk with their aforementioned images.
Nintendo encouraged this activity, but in the end, it ultimately was a waste of space as well as a magnet for people who simply want to vandalize a kiosk and make a mess. Not to mention the fact that you would always have one of those people that likes to waste the entire roll of stickers by taking dozens of pictures of themselves and placing them all around the display kiosk or anywhere else in the store.
Nowadays, the GameBoy Camera Printer and the Printer Refills are quite a premium, especially since not too many people were keen enough to buy bulk loads of either, so I wouldn't be too surprised to see the prices and demand for the Printer or Refills to increase in the following years through channels like Ebay, what with all the 'new' Nintendo Fanboys out there, who 'grew up' with the GameBoy Camera/Printer combo and are now just becoming a part of the 'workforce', earning a paycheck and contributing to society.
