I have the Disneyland 50th (from Maine Street towards the Castle) it has 50 hidden mickeys in it. I LOVE it! It has more then doubled in value, as they only sold a set amount. I bought a Gallery Proof.
Where there is a will, there is a way. This is not mine, it is from the internet, mine has a gold frame, but at least you can see it! It has 50 hidden MIckeys (well lots of them are not quite so hidden!) MIne also has a golden Mickey Ears emblem in the lower right corner, indicating it is a Gallery Print. Very cool
