Legendary rocker Alice Cooper will make a special appearance at the Monsterpalooza horror convention in Pasadena, California this May 29-31.

Attendees can meet Cooper for professional photo opportunities, but must first purchase event tickets and separate photo ops packages.

Pro-photo ops are on sale now through Celeb Photo Ops, while Monsterpalooza event tickets can be purchased on Eventbrite.

The convention will feature panel discussions, celebrity guests, and over 400 vendors selling horror-related goods.

According to creator Eliot Brodsky, Monsterpalooza celebrates the art of monster-making and movie magic behind the scenes of creating creatures and characters.
