What's the best way to safely remove sticky label residue from an antique tin?

I have this antique rectangular shaped nut tin that I bought at an antique mall in New York while on my honeymoon. I was able to get all of the paper price label off, but there is still the sticky residue of whatever adhesive was used to stick it on. On top of that, I don't have any nail polish remover or Goo Gone. What else can I use that will get the adhesive residue off without damaging either the tin or the image painted on it?
