Anyone have any idea what this trailer is? Masterpiece Optimus Prime Anniversary Trailer - eBay (item 320349471619 end time Mar-19-09 19:22:48 PDT) It's not the Justitoys one, the MP-04 packed in one, the Kooltoyz one, or the Mark's Project trailer. I asked the seller where it's from and he just said it looks like a custom, and it's 15" long. It just looks like some toy trailer with a sticker slapped on. What the heck?
