The ones you can buy are in my sig. Pic of Mickey on them, the ones for the 17th had the 50th logo and embroidered with July 17, 2005. You will not be able to buy those ones. The ones from yesterday DL would not embroider (you could do it yourself though) the regular golden ears they will embroider names on the back. My daughter wanted Minnie ears, so when we bought her Mickey ears, we had them make them Minnie for her. Only a few places that sell the ears can make the Minnie ears so ask. You can buy the ears at most merchandise locations throughout the park. There are only about 5 or so locations that can embroider on them. I think if you buy them that day you can have them embroidered for free at most of the locations. The one in the front (by the Steamboat Willie mural) uses a different type of machine and I know for most things they charge. I got the impression one time I was in the shop, that they charged to embroider the mouse ears also. You can buy the mouse ears, and then take it to the locations that will make them minnie. I can't remember the cost for this but it was under $2 (I didn't pay, and I didn't pay attention how much extra it was to convert them).
they also sell them in world of disney and DCA. I know they can embroider them in greetings, not sure where else.
