This issue of WORLDS OF IF Science Fiction magazine from April 1972 features stories from Isaac Asimov, Robert Bloch, Harry Harrison and others. 

The publication is a 1st edition, monthly magazine by Quinn Publishing Co., and as usual with lots of interior illustrations. 

In decent shape with usual issues associated with age - please note previous owner's sticker on inside cover - this can be removed.

Comes from a clean, non-smoking home.
