I used to have hundreds of pulps, now maybe only 20-30.
I try and post one pulp cover per day on my blog as I never get tired of the images.
Walter Baumhofer's run on Doc Savage was one of my favorites.
Artist Allen Anderson had a thing for space girls (and who didn't back then, eh?)
Norman Saunders cranked out an incredible body of work for decades, this one having two of my favorite bodies...
Graves Gladney (what a name, eh?) did some exceptional work back then... this Shadow proves my point.
This Air War by Rudolph Belarski (1944) is a powerhouse.
I'll wrap up with one by HJ (Hugh Joseph) Ward, whose covers were a bit disturbing. I've read that in later years, Ward was so ashamed of what he perceived as the misogynistic nature of many of his early horror covers, that he had a bonfire of the original canvases. Maybe Bruce, Grey or Rich can confirm?
Here's a link to several hundred other images (most of them the largest HD scans on the internet) set to infinite scroll (so there's no page turning). Sprinkled amongst the covers are a collection of fine BW interior art, too. There are also hashtags for individual artists, so you can make a day of it.
