Last known picture of Abraham Lincoln

[loetar44]

Kees, one more thought regarding your question. I believe it was Lincoln scholar, Mr. Harold Holzer, who discovered the error (that the April 10 date was incorrect, and the February 5 date was the correct one for the last Gardner sitting). I am not entirely 100% certain of that, but I think I did read it somewhere.

Thanks Roger, that leaves the question why Mr. Holzer came to the conclusion that the date was incorrect (what did he discover?) and why it was Feb 5?
