Two more cards have come in since my last comment.

Black Dog - “The photograph Announces...” - A nice, subtle colour print with a postcard backing - excellent use of “negative space”

Rai - “National Palace des Invalides, Paris” - Another colour print! This one though uses colour for special effect in a pinhole image of a building with character

Cards from 21 received, with just 3 (hoffy, Kav, Kc2edh) to come.

Thanks everyone.
