I don't think you can sign the ace, but by no means is that a drawback, signatures are nice, but people dont think like we do, and unsigned effects work just as well.
Lets not get too close to exposing anything. This is only about whether or not its gimmicked, speculation about what the gimmick is should not be on the forums.
Do you know mathieu's work? He creates the most amazing gimmicks.
What you consider gimmicks may not be the same as my idea. My idea is any object besides the two cards that facilitates in the effect. And yes I am almost postitive it is gimmicked.
If you don't know of Mathieu's work...
Hoping someone from t11 can confirm, but I'd say it can not be signed. Not that that makes the effect less impressive. Yeah you are right about no gimmick included, I am willing to bet.
www.mathieubich.com check it out to see his other stuff.
I am most positive its gimmicked like just about all of Mathieu's stuff. But don't worry about the gimmick, they are usually a new concept and extremely clean. And you will probably be able to make it at home.
sky_lark do you have any idea who mathieu bich is? If you do I can't believe you said no gimmick. Of course it'll have some form of gimmick, but like most of his stuff, you probably make it, which is why 85 minutes DVD.
