was it festival of the lion king or the environmental fable in epcot (the land)? - maybe a shop? i don't recall seeing this anywhere but it is a cool looking "thing".
That is a drawing of Mufasa's mask from The Lion King on Broadway. I have no clue where it would have been in the parks, FoTLK sounds like the best bet.....
