Each is spring steel with 1.75" button-like celluloid mounted at the front. Each have company name of Grand Rapids, Mich firm and all three say "The Flour The Best Cooks Use." However graphics are different on each with one being red and b/w while the other two are primarily red and green but one of these primarily promotes "Lily White" Flour while the second promotes "Roller Champion" Flour. This last one has a little of the black finish off the metal areas and outer rim has very small age markings but not distracting. The other two are Exc. and display Mint. An early and rare trio.
