A set of ten early metal Christmas tree light reflectors in punched tin (the holes do not go all the way through the metal). They're marked on the backs "Patents Allowed And Pend". I found them in one of my Christmas books identified as Diamond Ray brand, circa 1927, sold in boxes of eight. They're about 3 inches diameter and come in three different flower and star shapes.
The reflectors are surprisingly heavy, at least in comparison to later foil reflectors. Most have some light finish wear but no rust. There are no center prongs.
