The marble in my avatar is a 3 inch Robert L. Hamon. 
Ronnie, I think the marbles in your post are early ones.  I didn't discover Bob Hamon until 1992.  His work was greatly changed by then.  He had opened an art glass studio.  Before the shop was his, everything had to be functional - bowls, vases, perfumes, etc.  His Dad's generation thought art glass was unnecessary. Bob's dad had 2 brothers and they didn't do art glass either.  Joe Hamon, a cousin did a little, but had the parents attitude about art glass.  Bob Hamon's father was O.B. Hamon (Okie Boyd) His brother O.C. Hamon was the father of Joe Hamon.  Joe has a son and a daughter that learned glass.  The daughter, Cheryl Hamon Jackson still works glass.  I have marbles she made and a couple pairs of earrings.  Pretty!
