Michael I posted about these several months ago -- they are obviously not vintage and have been reproduced, most likely from the vintage plastic H&B bat rack sign that looks identical. ebay seller treasureray has been selling them for years -- he used to make it sound like it was one of a kind, coming right off the wall at the H&B plant. Now he has changed his description, with the same kind of vague wording used by sellers with reprint baseball cards.
Amazingly they keep selling in the 100-250 dollar range. Please see the link below.
