I have heard of a picture of Felix in his coffin, although I have never seen it. Just curious to know if a photo of Zenaida was taken after her death.
It wasn't his coffin, it was his bed, right after he went. It was very macabre and creepy. I was unable to bring myself to save it on my computer and now the site is down. I bet someone has it though.
As for Zenaida, she died in a home for old Russian emigres, and was not in good shape. She had suffered a crippling stroke a couple years before so I doubt she was anywhere near looking like herself, and was likely not photographed in that condition.
