June 25 (UPI) -- A 1935 letter signed by "Winnie the Pooh" -- actually written by illustrator Ernest Howard Shepard -- fetched triple its expected amount when it sold for more than $15,000.
Dominic Winters Autioneers said "Buffkins" was a childhood nickname for Harry Stopes-Roe, whose mother, Marie Stopes, was a close friend of Shepard. The Stopes-Roe family said Harry would often invite "Winnie the Pooh" to his birthday parties, and the illustrator would respond with a letter apologizing for the bear's absence.
The letter is riddled with intentional Pooh-esque misspellings.
"We are teribly sorry that we shant be able to come to your party on March 30th but we are going to be away. Thank you so much for inviteing us," the note reads.
The letter had been expected to fetch a top bid of up to $5,000 when it went under the hammer Thursday, but it ended up selling for a total $15,521.
Shepard, who died in 1976, was famed as the illustrator for Milne's books, as well as his 50-year tenure at Punch magazine.
