Sunday Morning Bonus Pulp: Complete Stories, February 1936
That "They Pack a Punch!" line ran on all the covers of this pulp for several months in 1936, and this particular cover seems to be trying to exemplify that. Inside are stories by Donald Barr Chidsey, Allan Vaughn Elston, Richard Howells Watkins, and C.S. Montanye, among others. I'm not familiar with James Clarke, the author of the lead novel, but I love the title: "Boozehead".
