Vincent van Gogh Virtual Challenge

The Vincent van Gogh Virtual Challenge from the Conqueror Challenges is kind of an odd bird in that it comes with these three images that fit inside the magnetic latch.  

The thing I don't care for is that these aren't the kind of thing that will stand the test of time. I mean, wash the thing and forget they're in there and you mess them up. Open this after fifty years and you just have to ask what these really are.

I don't know. Love van Gogh, but I'm not sure about this thing. I'm an adult and I don't want stickers.
