This pattern is called Fish Scale. Homer Laughlin manufactured this plate circa 1970s-80s.
The pattern consists of a fish scale design repeated on the verge and connected with lines, all in a deep forest green on an ivory body.
The sample sticker on the back reads DTH, (scribble) 8 plate, BC 1097, Fish Scale.
The 10 7/8 inch plate is in excellent condition with just a few stacking marks. Perfect to add to any Laughlin collection.
