Tiki Lounge Sign
It has been created by Etsy seller, Studio 724 using baltic birch, which has been distressed and given a blue finish, adding to its vintage look. It would look good hung above your home bar next to your Shag print. There is also a diner sign in a similar style. It costs around £30 plus extra for shipping, prices of which the seller will provide if you ask.
