A U.S. video game blogger has a theory about why a Sarah Palin-signed Xbox 360 was pulled from an eBay auction -- her first name appears to be misspelled.

Blogger Game Guy said the Xbox, which was purportedly signed by the former Alaska governor and 2008 Republican vice presidential candidate during a picnic before she announced her resignation as governor July 3, seems to lack the final "h" in the politician's first name, making it the alternate spelling "Sara," the St. Louis (Mo.) Post-Dispatch reported Wednesday.

The Xbox 360 had been listed for $1.1 million on eBay as item No. 300335581705 with only one bid before it was pulled for unexplained reasons.
