Okay, I've thought about this display of photographs...
They are really reminiscent of fae activity (and really reminiscent of the stylings of Froud)

But, compared to modern pictures of what I've seen of what I consider to be fae and wee folks, there seems a big difference that even the lens nor a 100 years can be blamed for.

I've never seen an authentic picture of an 'actual fae or wee folk' that looks like a cardboard cutout...
In the pictures that I've seen (that I consider authentic) the beings maybe overlayed, distorted, translucent, opaque or solid with one or more faces sharing the space, but they don't look like a paper cut out or a snippet from a movie.

I feel the 'Parting the Veil of Faeries' pictures are overdone... fae maybe the inspiration, but I doubt they were the real models... and if I am wrong, I will happily apologize for doubting his sincerity... but how would one know?, especially if these were the creation by a person that has since passed.

Which brings us to Cottingley Faeries... In my heart of hearts I think the 5th picture is authentic. It displays the familiar characteristics of modern pictures. Faces in the grass, where none need be... maybe the fae was mirroring what they see in the girls' faces, like the nature folks mirroring Alisa's puppy-dog.

I apologize if I offended anyone... these are just my thoughts.
