WW II Draft Cards--are they accessible?

Found on the internet one of my relatives:
Draft Registration Cards- 1942
Robert Minor Robertson
b. August 4 1888 in Fluvanna Co Va( 53 yrs)
Residence: RFD 1 Shipman, Nelson Co.Va
Race: White
NOK: Henrietta Robertson

Could there be any more information available?

I believe his father was Benjamin Robinson?
and his mother was Sally Humphrey
Would like to verify
