You will find it difficult to get most collectors of Thompson to agree on what is a "book."
For instance. Is "Lincoln's Grave" a book? "Claude's Big Trout?"
What I would consider books are not that difficult to acquire, running down all the ephemera is the real challenge.
I do need a copy of "His Second Campaign," cannot figure how all these years searching that I've never seen one.
I'm curious how many have both editions of "Lincoln's Grave?"
"Claude's Big Trout" isn't the easiest piece to acquire, but I've seen several copies over the years.
