Long before digital animation, streaming networks, and 24-hour cartoon channels existed, cartoons were a sacred, scheduled event. If you grew up in the golden age of animation, your childhood was defined by waking up early on Saturday mornings, pouring a giant bowl of sugary cereal, and waiting for the television tube to warm up. From the gritty, beautifully hand-inked black-and-white shorts of the 1930s to the colorful, wacky Hanna-Barbera television boom of the 1960s and '70s, these characters were our best friends. But as the decades rolled on, many of these iconic animated pioneers were pushed to the back of the vault. Today's generation might recognize the absolute biggest mascots, but they have completely forgotten the sidekicks, the theatrical short stars, and the retro heroes that used to rule the airwaves. We have dug deep into the animation archives to bring you 40 vintage characters from the 1920s through the 1970s. Scoring a mere 15 correct answers might sound like a breeze, but unless you were actually there to witness these classics, this test will absolutely stump you. Let’s see if you have the ultimate retro memory!
