Jim & Ruth Keegan's Two-Gun Blog: The Mystery of the Lincoln Stones [UPDATED]
Here's a very interesting article on Jim and Ruth Keegan's blog about a trip that Robert E. Howard and Truett Vinson took to Lincoln, NM. If you read their article you'll see that it pivot's around their recreating that trip in their The Adventures of Two-Gun Bob. Stone markers were never mentioned in Robert E. Howard's accounts of that visit. If you're interested in reading REH's account there are two places you can currently read it: The Collected Letters of Robert E. Howard and/or A Means to Freedom: The Letters of H.P. Lovecraft and Robert E. Howard.
The account is relayed by Robert E. Howard to H.P. Lovecraft. I'll be discussing that account in some detail in an upcoming article I'm writing for REHupa.
On that trip Howard mailed a postcard of the famous Billy the Kid picture to August Derleth and wrote on the postcard: "This card was purchased in Lincoln, N.M. from a descendant of a participant in the Bloody Lincoln County War."
Robert and Truett pretty much walked the entire area of the twon of Lincoln, NM. Had those stones from the Keegan article been there, I'm quite convinced Howard would have mentioned them in his correspondence.
Anyway, if you have the time, click on the link above and read the Keegan article. It's quite fascinating.
