I recently stumbled across news of a collection of NEW stories featuring Wandrei's underused pulp hero Ivy Frost - but would you believe it, Moonstone tell me it's already out of print - I guess it might still be available on Kindle.

I really think Ivy and his glamorous assistant Jean Moray would make a great TV series and can't understand why this hasn't happened.

Made me start thinking - what other forgotten pulp heroes from the thirties deserve a reboot - any suggestions?

No doubt in my mind.  The pulp hero most deserving a reboot is The Skull Killer, who never had his own title but was the hero on 2 villain centred pulps, The Scorpion and The Octopus.  And yes, some of you know that  The Skull Killer was brought back in the '70's in his own comic. by Pulp Media. But really, if someone is going to try pulp reboots whether in book form or as comic book, The Skull Killer is the one I would go for.

That said, I've always had a liking for a couple of Johnston McCulley "heroes", in particular, The Crimson Clown.  although I don't have examples of Detective Story Magazine, I do have a hardback collection of the Crimson Clown stories. Another one was a one appearance character, I think, Thunderbolt.  Yes, it'd be good to see revivals, but if they were to be in comic form, quality art and set in the time of the originals, please.

Yep - the Skull Killer looks pretty cool.

As an aside, I came across a pulp writer today - Day Keene - I've never heard of. I'll try to track down some of his books.

I also note his work is in the public domain in Canada - but can't find anything uploaded to the usual sites. It looks like he is sadly forgotten!

Years ago when I had a collection of paperbacks bought for the cover art, Day Keene was well represented. He wrote a lot of those Gold Medal originals, noir and tough guy stuff.

Well, I wasn't aware of Haffner Press. So thank you!
Re Ivy Frost, [and Jean Moray.] I'm coming to the conclusion [from my reading, and from the books on CB+, that there were actually a lot more strong females and female heroines in the 20's to 40's in fiction and movies that there were later in the supposedly liberated 70's to 90's.
That homepage has two Frederick Brown collections, which I can thoroughly recommend. They are definitely not run-of-the-mill. Good for your head space. Fred Brown was a thinker and liked also for his Audience to have fun. So, light, but also deep.         
Howard Browne's Paul Pine stories are great Private Eye stuff.
I see a collection of Moore and Kuttner's Michael Grey Mysteries.     
On the Canadian site, Faded Page,

Someone has been posting a lot of Kuttner's short Science Fiction stories. If anybody's interested.
Andrew, to answer your question,

what other forgotten pulp heroes from the thirties deserve a reboot - any suggestions?

1/ I would like to see more period Private eye, detective, mystery and police procedural material - Noir, not Cosy, in comic book form, but not rebooted, as in updated and substantially changed, but done period.
Not enough space here to go into it, but many of those characters just won't work and don't make sense in today's world.
My mind goes off in tangents of its own. Nero Wolfe just occupied it. And that's a big occupancy. 
The TV series with Timothy Hutton and Maury Chaykin was terrific.
Whole episodes here.

And here are the two 1930s Nero Wolfe movies.
