Here's the layout for the double-spread in JSA#24, which features the subway car from Captain Marvel's origin! This was really helpful to do as a small layout, and then enlarge and trace off onto the finished page, because both perspective points on the main shot run off of the 8x11 layout, but can be placed on the drawing table with ease, outside the image area. At full size, those perspective points would be hard to manage.

Here's the finished pencils, so you can see how the important stuff was settled before I got here!
