Signatures are for suckers. If you really want to leave your mark on a sheet of loose leaf, consider this idea from the fine folks at Stamp Yo Face! It's a custom stamp. Of yo face.
As cool little gifties go, this is pretty rad. For $65 (£38) you get a 2.5 x 2.5 cm rubber stamp. That seems a little steep, but wait—there's more! You also get the original hand-drawn portrait (and digital file), plus an ink pad so this thing is ready to go straight out of the box.
You get to play muse simply by sending in a pic of yourself, then sitting back and waiting for the magic to arrive in the mail.
There's also a couples option (good for wedding stuff, methinks), pets, a few choice celebs, and some mini quote bubbles, so you can tell HMRC what you really think of them come tax time in the most adorable way imaginable. [swissmiss]
