A pure repro auction would be a disaster for emovieposter. Little would sell for the amount necessary to pay the costs.
Some items may be repro, but have value. A well done, well understood repro of a poster that is out of reach for mere mortals is what I am thinking about. S2 repros, and that Forbidden Planet half sheet I own are examples that sell for a few hundred dollars.
The line also gets very blurry. Personally I consider fan club editions of popular titles to be nothing more than licensed reproductions. Star Wars, BTTF, etc all fall into this category. Yet the fan club edition often goes for more than the original. Why? Because it was never folded!
And that isn't even considering the Alamo Drafthouse and Mondo stuff.
In the end, I believe Bruce takes the correct approach by mixing it in and CLEARLY MARKING what it is.
