It is 8 x 10 and it is signed by Carl Mydans, the photographer.
I really want it because it is such a cool piece of photographic history and it's such an incredible image. Unfortunately it is probably also valuable, which means that we need to figure out how much it's worth and then I have to bargain with dad to see how much I can buy it for rather than him possibly getting a higher price on ebay. I do know that you can buy a different one of Mr. Mydans MacArthur photos from the LIFE picture collection, and that sells for $75 for the 8x10...
