Provenance comes "well-connected (in what we collect)" no matter where the dots may be and, as seen in Robert's sale... knowing the "previous ownership" along with the known (written), facts served well... even though not a word cataloged to be found CARO Collection)... and, the best part is that it was all found here, previously. Thus my lead post.

I don't know if any other well informative chip book than here (other than the exception of ChipGuide)...

I'm simply amazed at how the sale went down...
