It's a printed signature. I have a copy. by: Anonymous
Sorry, but the "signature" and note about the authorization is printed in each and every volume of the complete 25 book set; I have 23 of the volumes (Including the one you have) that I inherited in 1991 from my father, who inherited them from my grandfather in 1959. My Grandpa's signature is in every volume of the set I have, but his signature is real and varies slightly from volume to volume; all the Mark Twain signatures are absolutely identical, i.e. printed.
I just found the two missing volumes (Tom Sawyer, #12, Huckleberry Finn #13) in the correct edition (green boards, gold lettering) on ebay for $12 each. (Yes, I bought them.)

The book below listed by Steinway Books comes closest to your book. It was listed at $50.00. But is not signed.
"Harper & Brothers, 1906. Hardcover. Book Condition: Good. Hardcover, in Good condition, no DJ. Green cloth over boards with black title block on spine; gilt lettering; crown 8vo. Volume 8 of 25-volume set of Mark Twain's Works. Light shelf wear, clean and readable copy. Binding solid."
If your book is dated 1906 then Mark Twain could have signed it. He died in 1910.
When I look at signed Mark Twain books, I found this by Liber Miribilis in Palm Springs, CA:
"Harper & Brothers, New York, 1906. Book Condition: Very Good. This is the Hillcrest Edition of The Writings of Mark Twain Vol 1, and Volume 1 of The Innocents Abroad. Signed by Mark Twain on the fep. Top edge gilt, some ink (?) drops on cover and bottom of spine, corners bumped, head and tail of spine bumped, Signed by Author"
This was listed at $1800.
It appears your book may have significant value depending on condition. I would correspond with Liber Miribilis or take the book to a rare book dealer for an appraisal.
