I was going to post a funny/semi-snarky "gondor59 is trying to sell it on eBay" but then gondor59 came and did just that himself.

Lovely letter, and I know what you mean about trying to part with things like this, Jim!

Thanks for sharing, posting, and offering for sale.

Whoa! Out of my league!

(I think I might have some idea of who the letter might be to, though. But I'll keep shtum).

I promise you that it's not "Higgins."
