All of these cast iron items with bobble heads are of recent manufacture. I know of only two authentic Halloween cast iron items made prior to 1940.
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.
