glassware set

This was a collection of my mother-in-law's who just passed away at 97. She said she was able to collect it one piece at a time but I'm not sure if it was from a door-to-door salesman or what. I have what seems to be three dessert dishes, four goblets, a covered candy dish, a cruet?, and a three-footed plate. Does anyone know anything about what this pattern is, who made it, etc.? I don't want to just give it away or sell it until I know! Thank you.
