A very rare find.  I found these at a flea market in New York.  These are all new to me.  This is an antique Thomas Edison Diamond Disc Record.  They were produced from 1912 - 1929—a hard shellac material.  There are very thick.  This record is Edison # 50470. 
 
Side 1: The Colored Recruits, Coon Vaudeville Sketch with Banjoby Golden and Heins. 
 
Side 2: Whistling Coon, Sam Devere.  Edward Meeker and Empire Vaudeville Co. The outer edge is slightly rough with two very small surface chips or flaking.   It plays well, but it has a lot of background noise.  No original sleeve, but I have included a new heavy paper sleeve.
