Love those '75 Progressive proofs; cool that you were able to pick up a couple. Now you can go on the hunt and try and locate more of the Brock progressive proofs...
The '75 Kelloggs proof I think this is from the collection of a former employee of Xograph if I'm not mistaken. It's possible someone else had them slabbed at a later time.
