Set of 4 Vintage Fostoria American Star Base Beer Glass Stein Mug Mugs Tankard as is. Each appears to have 3 seams all around plus individual mugs measures approx. 4 1/2" Hgt. by 3 1/4" diameter across top open mouth + 1 5/8" side D handle flaring to 3 7/8" diameter across base.  Research shows "Production dates: 1933-1943 as Beer Mug and 1974-1092 as Tankard"

As acquired, preowned condition: See multiple & up-close outdoor photos, varied angles - all sides (few random individual bubbles/line indents within glass itself from factory formation; few have sporadic subtle darkened speckles within top rims; no chips nor cracks with exception of one mug that has approx. 3/8" crack line within base pedestal inner rim of thick glass not felt as penetrating to outer side +  few other flea bite/nicks -1 on a handle whiles others near outer rims of pedestal bases, shown - understandable considering Age surviva ~ prior typical enjoyed usage wear). Smoke-free home. Note: Vtg doily not included, prop cloth only to enhance items.
