Hello all, the original bill for the helmet comes from B & B Amusements in Brooklyn New York (where I've lived all my life) and the only company of that name used to run amusment park rides at Coney Island. The number is long defunct and I've been an avid collector for quite some time and never came across a memorabilia company of this name. The seller has little to no feedback and 0 return policy, that alone for such a supposed highly esteemed item is questionable. I am involved in the Fine Art business and the usual practice is that you have a certain period to review an item after purchase (but that's the real world not arrrbay). For further thought if you look at the auction for the Louis J Pearlman's Bankruptcy Auction there are no serious pieces rather all branded licensed memorabilia and with all the money pearlman was said to have had....well you get the drift. The appraisal is from R E Nardi who is a memorabilia collector/businessman in Florida (not a fly by night). Now I'm sure he has his own reasoning to say the helmet was authentic but as everyone here knows nailing down the authenticity of props and costumes have been plagued with inacurate claims etc. To quote my father (my mentor) who has been dealing in the Fine Art Business for over 40 years (MELINAFINEART.COM) "WHEN IN DOUBT DO WITHOUT" HAPPY HOLIDAYS MERRY CHRISTMAS AND A HAPPY AND HEALTHY NEW YEAR, Robert M.
