Vintage “Hippy Chick” Coffee Mug

I don’t know much about this, but it was made in England (see base). It is in excellent vintage condition, it holds 14 oz, is 5 1/4” tall with a top diameter of 3 1/2”. Peace sign inside the mug and in numerous places on the exterior. Colorful, beaded chicks in bell bottoms. Flower power! Super fun! Likely very late 60’s or early 70’s.
