The Alternate Realms site has several nice cardstock buildings, including some huts and a chapel. The page also has a couple of tanks and a science fiction walker vehicle. Finally, there’s a model of St Michaels tower on Glastonbury Tor (sp?).
Paper Models
Paper Star Wars Figures
This site has a nice selection of paper miniatures for both the new Star Wars movies, as well as the classic trilogy. They would be great for using with West End’s old Star Wars miniatures game.
Cardboard Superheroes
There are a lot of superhero miniatures rules out there — both free and commercial. So if you want to try one without going to all the trouble to paint some minis, you could try some of the paper figures on this page.
How To Draw Paper Soldiers
Matt Fritz has some good instructions for drawing your own paper soldiers. This would be a good way to try out a new period!
Paper Brick Building
Clifford Button of Paper Tiger Armanents offers a free 1/72 scale brick structure. It was inspired by a building in the Strand district in Galveston, Texas.
