Based in St. Paul, Minnesota, Peters Meats supplied hot dogs for Twins games and released this 26-card Midwest regional set in 1961 to celebrate the Twin’s first years in the city (after moving from Washington, where they were the Senators). The cards are pretty thick and heavily waxed since they were supposed to be used as packaging for meat products.

As the hobby library guy, I’ve always liked the advertisement from the Twins 1961 yearbook.

I’ve documented the set in detail on the oddball archive here: https://www.postwarcards.com/1961-peters-meats-minnesota-twins-baseball-card-set-and-checklist/
