Because I'm reading a lot of old books from the 60's 70's and 80's this year I was quite happy to order myself an copy of the top one for that reason and the rather lovely cover. I'll update artist info when it arrives, if its documented.
Sam, a 12 meter tall monument of a monkey cosmonaut, by sculptor Denis Prasolov. It was placed in Kronvald Park, Riga in Latvia. It pays tribute to all the animals that died in spaceflight survival tests before manned missions were attempted.
There are also some other versions of Sam and other animal cosmonauts in alternative format.
