Edited: please see the comment below the article from Charles Levinson, owner of this particular image. Thanks so much to Charles for getting in touch!
This is a bit of a strange one, to my eyes at least. It had no background information when I found it here - it certainly appears to be Victorian, but there isn’t much except the woman’s clothing and hairstyle to go on.
What’s making me curious as to its background is that the very close angle is unusual compared to all the other Victorian post mortem photography I’ve seen – I’m wondering whether it’s actually been cropped from a larger image.
I’m fairly sure that the markings in the bottom left are foliage from flowers placed around the coffin. The lady’s waxy pallor together with the degeneration of the print itself certainly gives a very eerie result.
