I made a similar discovery once. The garage at our old house was ready to fall down, so we were having it demolished. Before that happened, I inspected it and found a box in the rafters. It was full of pink depression glass, including a big pink bowl, several cups & saucers, 4 little pink glass ashtrays, and assorted small dishes. I had no idea that they were up there. Even my mother had forgotten.
