I have to be honest besides the pre-scream masks which are what say around 20 years old!!! man time flys seeing I was around the age of the characters when I first saw
the film in the theater!!! lol . But I really can't say on those because I Having never ever seen proof on anyone having one!!!! The ones with sold during the film with the funworld stamp or easter that are just as rare are the same exact mold!!! You have to see the mask was a cheap dime store mask which makes it so cool!!!! But a company will not do that for one it would cost them alot of money to because you have to one change it over in the factory in china or asia that they have been using for years. . They do not make these any more period . I have spent over 500 hrs searching the web networking they just are not being made. Funworld makes a new foam mask and the glow in the dark. The glow in the dark they cut way back on the materials used!!! to save more cash. You figure a penny on one mask multiply by a million adds up. I have compared the 3 out there also the blood pumping ones. The foam is nice but in bents and distorts very easy . And the glow mask again has less material around the head neck etc and is a lighter weight . And does look a bit different this could be a new mold for this run and the foam. Seeing that the original
ones we have are no longer made . A seller on ebay has a few he got in left behind in the pipeline . ThatS how I scored mine for 79.99 I thought was a steal!!! being new!!!!!
its hard to say when they stopped making them but I would say at least 5 years could be more or less. So again For pure collector purposes finding a pre -scream mask or what I think is cooler the knb mask would be a great find. But BEWARE I HAVE SEEN 3 PEOPLE WHO HAVE LISTED COLLECTIONS ON A PROP SITE WITH IN DAYS OF EACH OTHER ALL CLAIMING TO HAVE ORIGINAL SCREEN USED KNB MASK AND FUNWORLD !! WHO HAVE SOLD THEM TO GREEN COLLECTORS AS ORIGINALS FOR AS MUCH AS 1,500.00 TO 2,500.0 BUCKS!!! AND ALL THEY HAVE IS A OLD FUNWORLD KNB MASK!!! WITH NO PROOF ITS AUTHENTIC BUT THE WORD OF THE PERSON WHO SOLD THEM THE STUF!!!!!
