I just finished this book and I am totally psyched for the film. I plan to go to the local MN Con (CONvergence) as Abe this year and I'm in the process of building his trusty axe.
I know that in the film it also doubles as a gun, and at some point I do plan to do a "hero" version like the photo below (which ia a screencap from a real axe in the Lincoln Archives) The real hero prop is based on this:
...but for now, I'm just going for a static prop to twirl around a bit
So here is a screen cap next to my early mockup:
I have a lot more screen caps and such if anyone is interested. I'd really love to hear from people building this prop, or interested in it. I have a file for the axe bit that I'd be happy to share. I'm building the bit out of (3) layers of 1/2 thick black sintra. Should have photos of it tomorrow.
