Set of four Vintage Beauce Canadian Pottery Mugs

Mugs measure 3” diameter by 3.5” tall. Three mugs have no noted flaws, one has a crack in bottom of handle. Too is intact so it is held in place but may not be safe to soak. See closeup in last picture. Brown drip glaze with golden yellow interior glaze. Bottoms are marked Canada 600/4 and with the Beauce logo.
