A unique one sheet for The Public Enemy (1931) headlined an auction of movie posters on March 27.
It more than doubled its initial estimate, achieving $167,800 against a valuation of $80,000 (an increase of 108.7%).
The film starred James Cagney and Jean Harlow and is considered a hugely influential gangster movie.
The lot is of 40 rare movie posters discovered being used as insulation in the attic of a home in Berwick, Pennsylvania in 2011.
Heritage explained prior to the sale: "This incredible poster is a glorious testament to two major Hollywood figures at the beginnings of their careers, displaying the presence and allure that would soon rocket them to the heights of Hollywood royalty.
"This exceedingly rare style A one sheet is the only copy to ever surface! The poster has had significant restoration to address missing paper in the upper right side of the image."
Robert Gleason's original painting for the Halloween (1978) movie poster realised $83,650.
The iconic work shows a knife wielding pumpkin and was initially dismissed, as the studio wanted killer Michael Myers' mask to be the central image.
However, it soon came round to the idea and today the piece is credited as a hugely influential horror movie poster.
