Hi Art,

Because the military was segregated during WWI, the draft boards had to make a notation on the forms as to each man's race. While everyone had to register at the same draft board on the same day, the records were marked for race on that day. The "A" forms, those from June 5, 1917 had the lower left hand corner torn off if the draftee was black. Later, the B and C forms had a box to check for race.

Hope this helps,

Lee
