I make model graphicxs. Most don't know this.
No way!
Now that I think about it I'm pretty sure you've mentioned it once before
To the OP, get them re-cut, if you want take a high res picture before you take them, most graphics shops can usually duplicate them. Cost depends of course on complexity.
I use Goo Gone from Walmart, followed by alcohol to remove the adhesive residue.
