My husband and I recently bought a home that has this marble looking tile around the fireplace and in one bathroom. The realtor told us it is original to the home (built in 1925) and the tile was made in Evansville IN. Production was stopped in the 1920's as well. I believe the realtor called it "victor light" but I have not been able to find any info on the internet. Does anyone know what this is, and any history?
