I had a problem taking off the huge label (about 3"  x 1") about the bulb size which is attached to the inside/gold side of the shade.  I have been compensated and I repaired the shade. I could not get off the manufacturers label but that isn't so conspicuous.  However, the manufacturer should NOT attach sticky labels to the delicate inside coating.  You will note that there are none shown in the photo which is where they located.
