1976 Topps Welcome Back Kotter trading cards are one of the simplest releases of the era. With a small checklist and no stickers, it's both basic and affordable.
Based on the popular sitcom starring Gabe Kaplan and a young John Travolta, the set has just 53 cards. Comic-style speech bubbles add corny jokes. Backs add more dialogue in the form of "The Sweat-Hogs Speak."
