14x21.75" cardboard poster for concert that took place April 25, 1985 at the Pomona Valley Auditorium in Pomona, CA. that featured Anthrax and LA speed metal band Abattoir. This concert took place between the Feb., 1985 release of Anthrax's "Armed & Dangerous" EP and their second full length LP "Spreading The Disease" (which was released in Oct. 1985). Poster was signed at the time of the concert in black felt tip pen, vocalist Joey Belladonna adding "Spread It" and "Calf Rules" text. Guitarist Scott Ian has also signed, adding "Kill!" and "Not!" below Belladonna's expression of love for California. Poster has six staple holes/staple pulls crossing vertical center and 2.25x3" moisture stain at lower right corner. Pinholes at corners. Still displays Fine. Very few posters were printed for this show and they are rare on their own, let alone signed like this example. Comes with Hake's COA and Roger Epperson/REAL LOA.
