I don’t have a clue what that red machine/gear is, but that’s what makes it interesting. Like the concentric circles (both on the same block) surrounding it, the machine/gear was printed from a vintage advertising cut. The type is handset 18 point Park Avenue, from the American Type Founders. The sheet size is 5 x 7 inches; the paper is Mohawk Superfine, Smooth, White, 100lb. cover.
