I have not seen any, if I had, I would have bought some irrespective of the size.

To further elaborate on my prior responses, I would contact whomever made the larger decals regarding licensing issues. If they are on the up and up, they would have had to do the same research. More likely, they are a small shop who doesn't produce in "mass" quantity so likely would not draw any scrutiny and complying with the law may not be on the top of their list of things to do.
