Is that bottom one one of the original 1970s era Sheperd Paine dioramas? Kinda looks familiar...
He's pretty much the father of model diorama making. Worked as a professional modeller, on commission and for museums, his entire career. When Monogram came out with a new line of models in the mid 70s, they contralcted with him to come up with these "here's what you can do" full color 4 page pamphlets with a diorama he built. They were incredible, like a whole new way of building models.
Actually got to hear him speak once. He said he had under 2 weeks lead time from getting the first casting till turning in the pictures and writeup. They'd use whatever plastic was in the line, so the B-17 came to him bright pink. There were tons of the things. (I still have a few of them in my basement, though the models I made back then havent held up at all.)
He also said that all those dioramas were disappeared. For a while they were at Monogram headquarters, but by the mid 80s no one knew what had happened to them. So they only exist as pictures now.
EDIT:
Found it. Here's another view, of Shep Paine's original. I think the second photo is either another view of the same model, or a more modern duplication of SHep's layout.
