The original ‘Alice’ from artist Jim Phillips is very sought-after and easily sells for a few big ones, but the counterfeits are quite popular too nowadays. Also, the graphic must have been spotted by various manufacturers in the past, who appear to have put very different efforts in copying the original Santa Cruz model from 1989. So go ahead and waste your time looking for the differences!
This one sold on leboncoin.fr for about $20.
This ‘Racer’ sold for $124,50 (!) on eBay.
Here is one with a background that was never used on the original deck, sold on leboncoin.fr the same day it was listed.
