This is a Victorian pattern glass tumbler made by Doyle & Co., circa 1880's. It is their "hobnail" pattern in a gorgeous amber color glass! This is a fairly heavy glass tumbler measuring 3 7/8 inches tall x 2 1/2 inches across the rim - it feels wonderful in your hand! There are no chips, cracks, or damage (just the typical characteristics of antique Victorian glass - tiny bubbles, mold lines, etc.) which is quite amazing for this all-over hobnail pattern! It is a beauty!
