There's no credit given for the artist, which is too bad. I suspect the pictures are contemporary but they capture the look and feel of the covers from pulp SF magazines such as Astounding Stories. My favorites are probably the one of the shirtless man (though still wearing slacks and dress shoes) fighting giant ants with a bow and arrow, and one of a man doing a space walk while wearing a metal helmet and a suit - no pressurized suit or gloves. I'll be happy to have this calendar hanging by the desk at my office for the next year. But who's the artist?
