With some imagination (and help from the lady who had it), pretty sure it came from a trip taken to California during the late 1960's-early 1970's time frame.

I'm not sure if you will be able to see them in the pictures, but.......there are "charted lines" like you see depicting where certain airlines fly, imprinted on the globe.  Makes me think it might have been an airline give-away?

Anyway, I'm a sucker for globes so this called to me.  Hope someone else will see its charm.
