Antique Ruby Flash Mug Diamond Sawtooth Pattern Antique Ruby Flash Mug. This mug has a diamond pattern sawtooth band type pattern around the bottom, the bottom is ground and it has an applied handle. I would estimate the age this piece to be early 1900's, possibly older. It measures 3 inches tall and about 2 1/2 across the mouth. It is really good condition, there are a few pinhead spots and some slight wear round the rim, not really that noticeable unless you are holding it up to the light, there is one pinhead size chip on the flash right about the pattern band otherwise no chips or cracks. It would be a nice addition to your collection!
