But after coming across this interesting website devoted to "League Sets" http://skedman15.tripod.com/schedulesgalore/id22.html, I started thinking about other, older League Sets not mentioned there, and now I'm getting excited about trying to fill in the blanks for the Schlitz League set. I have skeds from this set from 1970-79, but it appears from this website http://www.astroland.net/skeds.html that at least one team, the Astros, had a Schlitz cover going back to 1966 (put your mouse over the '66 and '70 Astros schedules to see images of Schlitz covers from those years).
1. Did all teams participate in the Schlitz League set? For example, I've never seen an Expos sked with a Schlitz cover.
2. What year did this League Set begin?
