My hubby has returned from the post office where he sent off an envelope to Battle Creek, Michigan. He had collected enough box tops and such from Kellogg's to get a free cholesterol testing kit.
"Do you know what I last sent for from Battle Creek?" he asked me as he was assembling his request forms.
"A decoder ring?" I guessed.
"Close! It was a space helmet from Space Patrol!"
(A little research has determined that Space Patrol was not sponsored by Kellogg's, but by Ralston. Kellogg's instead sponsored Tom Corbett Space Cadet. And I leave you to your own musings on that.)
