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.
