You can always tell when there has been a warehouse sale, strange things appear on ebay. <img src='style_emoticons//unsure.gif’ border=’0′ style=’vertical-align:middle’ alt=’unsure.gif’ />
Some of the things that are sold from the warehouse sale are mistakes or unfinished solids and the dealers “fix” them and sell them on ebay.
One example- the enamel on some of the flags falls out and if it doesn't break you can glue it back but some sellers sell it without the enamel piece. I have seen several on Ebay. The clown may have been an unfinished one and the seller tried to “fix” it. I don't think you can call these prototypes. I call them broke.
