I cant really speak for any of the other paper manufacturers, but I have got a whole shedload of Workldworks stuff, which in some cases can be suitable for Pulp games.
As a rundown
Shellendrak MAnor - ideal for old manor houses and the like, it does have a nice roadster which is very cool. Think the o'connels residence in the mummy II. Return to Shellendrak gives a further set of roadsters, which we are going to use in a gangster style car wars of the roaring 20's
This one has a practice turret attached to the roof, it still needs the armour plating on the windows...
The Legend of Skull cove is really handy for native village, dugout canoes a fab skull rock, not to mention jungle type plants, rocks, cliffs and jetties etc. THis is the one that I am using for my pirate game and will be using for my pulp game too.
This is the skull rock - part of a pirate game we did.
BAsically I have loads and loads of the different sets from worldworks...sometimes I get the set for a particular item....
Hope this helps
Cheers
