I swear I have seen a B&W candid photo of Hoover in his back yard wearing a dress. It was years ago, and I can't seem to find it with image search. It could have been faked, which was my first thought, but as far as I could tell, as a graphics professional, it did not appear so to me. It looked like it was his gag, like he put on a dress as a joke. iirc, Tolson was in the picture dressed causally, and they were both laughing, not very close to the camera, and the picture did not appear staged. It looked like he was hanging out in his back yard in a dress as a joke and I assumed it was the (false) source of the rumors that he was a transvestite, like, if someone had seen it in 1950 they'd be sure he was, but to me it just looked like a man in a dress goofing off, and there's a huge difference. He wasn't wearing makeup or a wig, and he was smoking a cigar. It would have looked like a Halloween scene, except Tolson was dressed normally.
