I've been working on the few engravings of Richard Baratz and found a Gene Hessler reference to his work on US commemorative panels, but I can't seem to find the actual panels.
What I'm looking for is a commemorative panel with a picture of an olympic runner. This would most probably have been issued for the 1984 Olympics.
The second one which I can't find is a panel with a portrait of Martin Luther King. I have a picture of it.
Could anyone tell me which panels these are and which stamp issue they accompanied? Or maybe even be able to post a pic?
