Google's cache of the yearbook has the text, formatted haphazardly, but not the pictures. The name Blasey appears exactly three times: above some sort of dedication "To Mom, Dad, Tom, and Ralph: My gift is my song. ...", in a caption below what is ostensibly a photo of cheerleaders, and as an entry in the index pointing back to pages 76 and 210.
As a side note, one would think that whoever this blogger is, he would at least have provided a cover shot of the yearbook cover to substantiate that it is indeed from the school as well as the years Ms. Blasey was in attendance........
He should have posted the unmodified PDF on Dropbox or somewhere and linked to it. And I don't get why he bothered to redact anything.
I suspect the person that did the redaction was trying to protect the students who were not involved in any of this.
