Hires, A&W, Barq's, Mug, Sprecher, Dad's, IBC, Berghoff's: What's your favorite brand of rootbeer? Ask me and I'll tell you. I like my rootbeer to be Bakelite. Here's a medium-sized button in faux tortoise, or what we Bakelite fans call "rootbeer" in our funny, food-obsessed way of labeling the vintage plastic. Probably dating back to the 1930's, this old button is carved with a bubble-like motif going around its rim. Looks like a candied refreshment.
