I have bought a coloring book from a con for about 8 dollars once, it was very nice and detailed to a point and it came with a plastic cover and crayons. I have to say if I bought this I would pay more just for the line work alone!! That is not only extremely detailed it give the effect of 3D on a non-colored-2D plate! I mean that would be fucking awesome to color!!! I wouldn't know what to do with myself! owo
the price depends on what type of paper is used. if the paper is a nice heavy weight, that someone could use copic markers on, then yes I would love one. If the paper were to be almost newsprint like in other more traditional coloring books then I would probably not be interested.
I would definitely be interested. But, would it been a standard size of paper? (9 x 11 ish) As for what would apply to me, I would say a mix. I like them all...Or maybe you could have a few different kinds.....Kinda like theme or something.
