This 1965 Woolworth's ad is truly a work of ghoulish greatness!
Then in 1966, Woolworth's gave the world this amazing ad mixing super heroes with monsters. I found the same one printed in the same year for Woolworth's short lived spin-off store, Worth-Mart.It's so nice it's "Worth" seeing the artwork twice!
Apparently Woolworth's didn't know the difference between Micronauts and Shogun Warriors but that's okay because in 1978 not too may parents probably knew the difference either. Most probably thought Baron Karza (Sho Gun Warriors) in the top corner was Darth Vader's goofy cousin.
