vintage Frankoma pottery mugs lot, collection different patterns green brown glaze mismatched cups

Lot of FIVE different mugs, all Frankoma pottery in the green / brown mottled color, matte finish glaze. All are a fairly bright jade green with deep brown - not the more muted colors you sometimes see in Frankoma.

All are used, and show glaze crazing mostly to the interiors. Two have chips, see photos. Sounds worse than they look in real life! These display well together, size ranges from 3 1/2" to 4" tall.
