Awesome estate sale find appears to be autographed to EK danford and Kimberly. Maybe signed by Bing Crosby!  There is a number at the bottom right corner that reads p1452-1267.

I do not have a certificate, but if it were to turn out to not be authentic I would of course accept the return. If you do have any questions or would like more photos, please feel free to ask. Please check out our other awesome collectibles and have a wonderful day!
