Another silly vintage gumball vending machine card.
I’ve never really understood the attraction of sour candy, especially a sour candy for kids. At work, I sometimes give a lollipop to really well-behaved little ones and the Charms Sour Apple Blow Pops are as popular as the sweet Tootsie Pops. The graphic artist here went to the trouble of putting a sour pucker face on every grape, although to me some of the grapes look a bit depressed. Ever wonder why humans respond to sour taste with a pucker face? There’s all types of theories on the internet.
