Two of the Indian design prints that were in the Contemporary Resort from 1971-1985 are for sale on eBay with the auction ending on April 16th 2009. They are very rare and you can find them on eBay by searching "Mary Blair theme park art".
I have the set of 5 from the Contemporary Resort from 1971. When they remodeled in 1980 my mother in law bought them, she worked for Disney contractors. Yes, they are rare not many survived the remodeling. Four 23”x26” and one 36”x26”
