I think this is a woman (in the middle of the postcard) ready for a bath...
A male puppy trying to get the attention of a female puppy. She's not having any part of him as she looks away with her nose in the air.
Two faces (with sunglasses and big laughing open mouths) looking aside.
I saw two seahorses facing in opposite directions - so I think we all saw different things. I like that Eva saw something in the non-ink space - that's quite original.
