Siblings Sid and Marty Krofft were the architects of television shows and surreal puppetry that inspired generations, garnering the biggest influence in the 1960s and ’70s with designs for “Hanna-Barbera's Banana Splits” and “H.R. Pufnstuf.” Now, La La Land Gallery curator Kii Arens has assembled a group show to pay tribute. The Krofft Super Art Show opens on Aug. 26 at the Los Angeles gallery.
