Where to get figures for Pulp!? That's a question I get asked. Fortunately there's a fair few places you can get some pulpy goodness in miniatures from online.
Obviously my favourites are the Copplestone Castings range of High Adventure and Back of Beyond. You've got some great armed archaeologists, assorted dinosaurs, explorers and yetis. Plus the Gangsters range give you thugs and guys with tommy guns. Mark's a nice guy too, so deserves your custom.
Another recent discovery is the Artizan Designs collection of Thrilling Tales minis. There's a great collection of aviators, police, cultists, nefarious villains and even some suitably nasty looking robots. Personally I particularly like the Sky Pirates.
Some of the RAFM Cthulhu miniatures have a suitably pulpy feel. Some of the sculpts are a bit cartoonish for my liking though.
Pulp figures produce a variety of options too. Again, some dodgy sculpts, but they have some unique options like the US Rocket Corps and Agents of Justice that should tempt you.
