These were not photos, they were watercolors and the artist just painted people as he saw them in general and the first watercolor was not of a funeral, but rather someone sick in bed (It was supposed to be his deathbed).
Artists dont always have models (These were not meant to be masterpieces) . I would have loved to have taken of picture of these watercolors as I was fascinated by them, but it wasnt allowed 🙁
Its amazing they have survived.
