I’ve read about a dozen “Spider” pulp reprints. Indeed, sometimes rather shockingly violent. Never had an original issue of one, although I still have a box of old miscellaneous pulp mags, covering most genres.
I stumble across ‘Shadow’ and ‘Doc Savage’ pulps now and then, but a copy of a ‘Spider’ pulp is a real find...scarce and expensive. I see that someone has posted a decent copy of ‘The Spider’s Web’ on YouTube...have to check it out when I get a bit of time.
