Circa 1936-1946: Fiesta pottery price lists once included a coaster. There is speculation that the center relish piece also doubled as a coaster, although we can attest that it does indeed make a fine coaster, it is also a treat to find the spare vintage fiestaware relish tray pieces to complete your own sets. Please note a couple extra kiln chips on the bottom of the insert, from the kiln and in the making. Marked in the mold on the bottom with the impressed "fiesta HLCo USA". Measures 3 1/4" across x 1" tall.
