|Here’s a little bit of promo history from the (not made up!) Waxahachie Daily Light about the popularity of depression-era glass. For those of you who don’t watch Antiques Roadshow, “Depression-era glassware was a cheap and colorful product given away at the movie theatres or with extra-large bags of flour at the grocery store.”
Apparently, the switch to mass production in the early 20th century made glass an affordable promotional product even during the depression: “Many stores used the glass as a marketing incentive. One pharmacy advertisement from the time boasts a free hostess dish with the purchase of a 25-cent tube of toothpaste (and two dishes for a 50-cent tube). General Mills created a large cross-promotion based around cobalt-blue milk pitchers with Shirley Temples face on the side.” The era of depression glass is over, but promotional glass remains to this day.
