As cool as an ~ATH book would be, I suggest sickles just because carrying a book around a convention center gets super irritating. With a sickle you have a handle and can hold it without thinking about it, a book you have to have one arm around and balance it and blah blah blah.
I had to carry a book once it got too troublesome after a while so it ended up in my bag after like three hours. Plus it limits how you can pose for pictures, there’s not much cool stuff you can do with a book.
I can’t wait to see it, post pictures!
