Here's the item description:
745. "Donald Duck" WALK-AROUND COSTUME ENSEMBLE FROM DISNEYLAND. (Disney, ca. 1960's) Costume ensemble consists of a small turquoise velour sailor-style jacket with a single silk faille strip at each cuff and along the border with a matching short cape attached along the shoulder, and a vintage cherry red velvet bow tie, attached at the neck to position across the jacket front closure This remind one of the earliest examples of a Disneyland Donald Duck walk-around costume known to exit. In park used very good condition. $3,000 - $5,000"
Profiles in History only included two pictures of the shirt, sadly. Also, they displayed the shirt the wrong way. You can see in the front the zipper and/or velcro. That is meant to be towards the back not the front. The listing does not show a Disneyland tag or label inside the costume. When collecting Disney costumes, the tag is very important and key. The starting bid is $3,000, which it might be a bit too much for a velvet shirt. Quick fact, on the 70's Disneyland costume manual, Donald's shirt is referred as a "midi-blouse" not as a shirt. The "cape" part of the shirt would be attached to the head's neck fabric. If I had a spare $3,000, I would buy it and add it to my growing Disney costume collection. But for way less money, I could make a replica one and it would look much nicer than this one.
