6 antique porcelain animal knife holders

Set of 6 zoomorphic porcelain knife rests: we see lizard, cricket, rabbit, birds ... a strong favorite for this set probably from the 20s or 30s. Sold in their original cardboard box, with a very patinated and very flea market look as we like. The box measures 19.5x14cm by 5cm high. The knife rests are 11cm long and up to 12.5cm for the longest. They measure from 2.5cm to 4cm at the widest parts.
