Fits any lamp! So easy. It is a most unusual type of lamp shade, because it has no clamps to clamp onto a light bulb. This sits on the top of a light bulb. It is hexagonal with floral repeat that is the same on every panel. Appears to be canvas. The gold panels are actually paper. There are some slight discolorations as well as rust on the rods, but this doesn't show to the outsides. Possibly some tiny mildew or aging stains. It is 5 1/2 inches deep so not very large. 1930s to 1950s... Offers welcome
