I thought this Oswald photos article was interesting from over 40 years ago.

Dallas police evidently found three negatives and at least two prints. The Warren Commission got only two prints and only one negative. Besides the traces of the one Sgt. Kirk uncovered, the evidence of another negative having been seized by police was obtained by the committee from two other sources.
That's such BS. The "blowup" was a Warren Commission exhibit, CE134. Kirk didn't "uncover" it. And the original negative is "missing". Damn the luck.
Handwriting expert Joseph P. McNally agreed that it was not her writing.
Funny. I thought "Richard" was a fan of handwriting "analysis". But he still thinks it's "likely" that Marina wrote this anyway. Go figure.
