I found a medium size bottle (appx.7" tall) at a house dump. Everything was on or near the surface and appeared to be from the 50's or 6o' - nothing really old. The bottle has embossing that reads "Dr. YY. Caldwell's, Montcello Illinois". Wish I knew how to post pictures, but I don't. I'll try and get my son-in-law to stop be and show me how and then I can post a picture of it. Untill then, can anyone give me any information on YY. Caldwell?
