Wish I could find the article.Whatever pile or file I put it in do not know now.I do recollect a picture of the Bill of Exchange and also several recently discovered checks drawn on Canadian Banks and if am not mistaken some were direct from Thompson and some CS Senator to Booth.
The article and pictures,about 3-5 years ago were in publication of either:
The Society of Paper Money Collectors SPMC or
The American Society of Check Collectors ASCC
Just recently reread some of the Lincoln Conspiracy books.Is obvious Booth did the deed.But,,,there are just so many unanswered questions surounding the incident.
