Thanks to Dick DeBuse for this information.

This Globester ad is from 1959 when they were resurrected by Hi-Lo. They were originally made in 47-48.  Note the "Globester safety scooter" label on the later model.  In 59 they came in red and gray as well as yellow and brown.  The frame was a single aluminum casting.
