Peanuts creator Charles M. Schulz once had a crush on a woman 23 years younger than him. He sent her love letters that included drawings of his beloved Peanuts characters that included her name. He even snuck her into the Peanuts strip once or twice.

Tracey Claudius,the woman stole his heart and turned down his marriage proposals twice, was told the letters will get anywhere from $250,000 to $350,000 at the Dec. 14 auction.

According to an article from KMBC on MSNBC, Claudius met the cartoonist on March 16, 1970, while accompanying a friend on an interview assignment. She came along as a photographer but afterward admitted in a letter to Schulz that it was a chance for her to meet her idol and thank him "for all the enjoyment Charlie Brown and that 'stupid beagle' provide me."

According to Sothebys, there are 44 letters totaling 56 pages, including 22 original drawings of some of the characters, primarily Charlie Brown, Snoopy and Lucy. Many are signed "Sparky," Schulz nickname.

A biographer for Charles M. Schultz was told about the letters and the woman that he was taken with and puts the date that he was in love with her and asking her to marry him in the time that his first marriage was ending. Although, he said that he had to stop calling her because his wife discovered the long distance bills.
