I have owned these lovelylittle ramakins for over 30 years , and never tire of looking at the " Picassoesque " images on them.
Three have the same markings of impressed vallauris and hand written name and initials R G ( or R C? ) . the other just the impressed mark and hand written what looks like to me as Jacquit . they all also have the letter Y .
I'd love to know the potters name etc..
they are approx 7 " long at handle an 5 1/4 " diametre bowl and 2"max hieght.
Made from hand painted terracotta clay circa 1960's I guess.
