Stangl BROWN Town & Country Set of 4 Mugs, spongeware cup pottery vintage NICE

Description

You are bidding on a set of 4 Stangl Brown Town & Country spongeware pottery mugs, vintage.
These mugs are free of stains and cracks. They all have a slight bump or very small rough spot on bottom (not on rim) feels like a bubble prior to glazing? One mug feels like it may have a small chip on bottom (I circled with red on the last picture). They are very nice and high quality.
Comes from a smoke free home. Thank you!!
