Does Anyone Know This Mask?

[🪦 Chainsaw ●]

I\'m pretty sure I\'ve had this mask for just about 20 years, so I guess this is my first piece (I\'m just now getting into collecting). Got it for Halloween that year, but well...it\'s seen better days. I thought I\'d post some pics to see if any of you guys can tell me anything about it. It has the following text stamped into the latex on the back...

"1984 The New Line - Heron Venture
O/B/A The Third Elm Street Venture"

Kinda contradicting since the \'third\' Nightmare was released in 1987, but I\'m not sure that\'s what it means. Anyway...on with the show!
