Yes.
AN ACTUAL yearbook, not cropped photos with inserted captions. How about a photo of the ENTIRE page? Since when did they TYPE captions in professionally printed yearbooks? Anybody might have, at any time, typed or HANDWROTE those captions, then photographed the result and cropped it for these “courtesy” photos that have no provenance. I was expecting a high school yearbook, not grade school.
Oh, that signature sure looks like his.
