1971 Dell Today's Team Stamps

Was able to pickup this cool Fergie Jenkins card this week. This card was from 5 years before I was born so had never heard of these until it popped up on a WhatNot show and for $4 thought it was worth a pickup.

From what I can tell these were kind of the precursor to the Topps sticker albums that I remember from the 80s. Looks like there are 600 stamps in the series and looks like there are quite a few Cubs.
