Rare Disney Tiles

I found these years ago on Ebay and I'd like to know more about them. They are clearly not the usual souvenirs sold to the public, although were perhaps sold as keepsakes from construction remnants. I cannot find anything similar anywhere on the internet, except for the ceramic redwood tree tiles from the Grand Californian, of which I also have one.

I should mention that these tiles are roughly 8-10 inches and are 1/2 inch thick.
