Here's a link where you can download the Sheperd Paine diorama pamphlets that were in the Monogram models back in the 70s, maybe even into the 80s. They were four-page pamphlets that really fired up the imagination when I was a kid showing what could be done. These can be a great help, no matter what kind of models you are doing. I'm not sure how many models had these, I look back at this site every once in a blue moon and sometimes there is another one or two added.
