A representation of a wall climbing lizard/gecko from bicycle chains. Roughly 2.5ft/80 cm in length, it is the most popular size of lizard sculpture.
He has metal nuts for his toes, the holes in the centre allow him to be hung on a wall easily. Indoors a picture hook is perfect, outdoors I recommend a screw for a more secure fixing.
I can make you your own example to order at £215 (inclusive of post and packing to U.K. mainland addresses).
