well its not really plastered, it will be my logo, name and contact info, in an elegant way. 
And my wallet prices will actually be cheaper per wallet than before, but they will have to pay twice as much as before, to cover the additional costs. so 3x as many wallets for 2x the price. Even cheaper if they go for 48 of the same design.
Branding the work isnt a new concept, virtually everything out there has the creators logo and/or name on it.
My main concern is people wont like the heavier paper, or the fact the wallet will be slightly more narrow than the average wallet. But in reality it will be 1/8" narrower than my regular large wallets, but 0.5" longer.
im also playing with the idea of putting my logo as a watermark on my prints.
I tried this a while ago but it isnt something I stuck to for very long. But I am trying to work on my brand recognition/value.
