Year with the Yeti

On a forum called The Yak Shack, the user terryweasley stated that he owned an authentic Year with the Yeti prop, and then later posted some high resolution scans of the book's cover. The Rumihart Books logo is visible on the lower left corner of the back cover (it's similar to the design embroidered on Lockhart's quilted vest in the dueling club scene). Do you think this is a reliable enough source to incorporate the information into this article? Starstuff (Owl me!) 14:29, December 29, 2009 (UTC)
