Ross Auctioneers • Northern Ireland , by Dr Plip on Feb 22, 2015 12:48:57 GMT 1, I don't know about the genuineness of the tenner, but I know that authentication services like to use hologram stickers on autographs and things these days. It looks like one of those. You pay them to see if your item is genuine, they then Google image it and compare it to others, then they yay or nay it (usually yay, to keep you coming back), then they put a shiny sticker on it and send it back to you along with a piece of paper that's a physical manifestation of their expertise.

They should be individually numbered so you can correspond the item with the relevant paperwork back in some guy's bedroom. If you can read the tiny writing on the sticker, you might find the company that issued it. Of course, you can get stickers that just have the words "Authentic" or "Limited Edition" on them.

Lots of places use them these days. I know of a few shady autograph folk that put hologram stickers on faked photos, just so they look like the real deal.

You'd be surprised how easily impressed people are by hologram labels. I myself never leave the house without applying several to my chest.

What we should really be asking is "If you knew you had a real Banksy print, would you allow anyone to put a sticker onto it?"

Edit: *Legal Disclaimer* Of course, I could be wrong and I know nothing about this or whether Mr. B has used shiny stickers on these notes before. This could be a genuine tenner and worth squillions. What do I know?

"I don't know much, but I know I love youuuuu"

"That may be...all......I.......need...to know...."
