This is a set of 3 vintage Mid Century era Nasco Japan coffee/tea mugs. All three have the Nasco foil labels on the bottoms. They are white with two shades of green checks. They have the look of vintage diner or restaurant ware mugs. The mugs are in very nice condition without chips or cracks, no fleabites to edges, no crazing, and no liquid stains in the interior. There are small dimples through-out two of the mugs due to the manufacturing process. Green paint is in great condition and not faded or scratched.. some paint loss on one of the checks on one of the mugs (top corner of check near the handle). I am not sure of the material (china or ceramic) but they are very light weight and easy to hold.
