Charming vintage keychain, venticular Flicker Card design by Vari Vue.
Flicker style, “Hullabaloo Twist” dancers in a venticular design, move back and forth as you turn the image.
Video shows it best – take a peek!
I believe this to be a promo from the 1965 NBC show “Hullabaloo”, only around for 1 year.
Excellent condition.
2″ x 2-5/8″
