This is a new item, almost certainly made off-shore within the past year. It is nicely detailed and would be fun to have as part of a contemporary display, but it isn't old. The detailing is too fluid and the appearance of the reverse is inconsistent with the one truly vintage Halloween doorstop I have seen in person - a haunted house.
Fakes, etc.
I'll begin populating this page with photos of reproductions, fakes and fantasy items as I see them listed on eBay, Etsy and other such sites. Hopefully, collectors will refer to this page to minimize the occasions reproductions, fakes and fantasy items are unknowingly purchased. If you see something on this page that was sold to you purporting to be a vintage item, immediately send it back for a full refund.
