Hanna-Barbera turns 70 this year, and although the skies are, alas, still free of Jetsonian flying cars, the Paley Center for Media is celebrating in a Grape Ape-sized way. “Yabba-Dabba-Doo! A 70th Anniversary Salute to Hanna-Barbera” explores the history and creative legacy of limited animation pioneers Bill Hanna and Joe Barbera, who first collaborated in 1939 on Tom and Jerry cartoons. An exhibition on view through September 10 at the Paley Center’s Los Angeles outpost is a treasure trove of cartoon history, including Iwao Takamoto‘s first doodles of the Scooby-Doo gang, early designs for The Jetsons, and photos from voice recording sessions of shows such as The Flintstones and Johnny Bravo. If there is any justice in the world, Laff Olympics, Space Ghost, and Snorks are also prominently featured. Meanwhile, Hanna-Barbera’s big 7-0 is also a perfect opportunity for us to call your attention to this clip of Snagglepuss, as portrayed by Bobby Moynihan on Saturday Night Live‘s Weekend Update. It’s terrific, hilarious even.
