A 1960s promotional photo of Ruth Prins as “Wunda Wunda” floats atop the corresponding original costume and hat, loaned by Prins’ daughter Debra. Though her attire was quite colorful, many of those who viewed her on TV when they were children remember her only in black-and-white. (Clay Eals, with design assistance from Leslie Howells.
