PK Unity Golden Pheasant Small Bowls (Set of 3)

PK Unity Germany 13 Lusterware Green Bordered Golden Pheasant Small Porcelain Bowls (Set of 3) Vintage. 5.25”D, 1.75” depth. Very pretty! Very old but can’t seem to date them as I can’t find any like these exact bowls. Preowned, there is faded areas throughout pictures & green border on the bowls but they are all very evenly matched with wear (see pics). There is also a very small chip on the rim of 1 bowl (see last pic). No cracks, major breaks, stains or major damage. Clean, smoke free home.
