In talking with Ed Miarecki this past weekend, we discussed that he puts items up for sale on eBay from time to time. This week he has two interesting items.
One is a shuttlecraft casting from "The Osiris Chronicles" which was a production to be made by Star Trek veteran Joe Dante and Paramount. We have seen some of these items in the IAW sales as the items were stored with all the Star Trek assets. You can read about this item and "The Osiris Chronicles" on John Eaves web site here.
The other items is what Ed calls a miniature "master" though I would speak to Ed if you are interested. I don't think Masters were made from foam, but I could be wrong. Ed sells a lot of good stuff, and he knows of what he speaks, but just check with him on this one. You can see it here. A few weeks ago Ed had a casting of the Ferengi filiming miniature that went pretty high.
