Depression glassware?

Depression glass seems as strange description, but these kitchen items were named after the era in which they were produced. The Great Depression, a ten-year economic slump that began when the stock market crashed in 1929, was also called the Dirty Thirties in Canada, where it coincided with a devastating drought.

This dish is one of a few surviving items from my mother's kitchen, and now it's cracked. Not sure it's depression glassware, but the thought of not using it at Christmas is a bit depressing.
