I found these letters in an old cardboard box in Upstate NY a couple of weeks ago and thought they were just the most beautiful things. And, I could spend hours playing around with them forming different words and phrases from what is at hand, which makes for quite a fun game. There is a small gold triangle among them announcing that they were produced by the Radiant Letter Co, NY (what a great name!), earlyish 20th century I would think. The gold seems to be true gold leaf and is very radiant indeed. All sorts of things one might do with these.
Large 3 7/8" tall. Small 2" tall. All in good shape, and all pictured included.
