cool item but the crude imperfect construction might suggest its a one off
having said that, the art on the cover is great
need better close up pics of the art and the imprint method
IMO

JTW, you should send them pictures, as it seems they don't have any of your exact box http://www.matchsafe.org/Museum/StandAlone_Index.aspx
Maybe they'll figure out the origins of these and let you know... So don't sell it too soon
