Nothing about these acetates are warped except the songs on them -- original master recordings from MAD's five commercially released albums from 1959's "Musically MAD" to 1980's "Up the Academy". The disks are marked with yellow handwritten notations such as "Mad -- It's a Gas", "Mad LP" and "You're So Infantile", as well as other tracks mastered by the Transco Studio including Dionne Warwick's "Message to Michael". Acetates are in immaculate conditon and come in the original sleeves.
