The Rainbow wood was made in the standard Duncan Tournament shape, but with rainbow painted colors, faded one into another. Like several other models from this era, it also featured a foil sticker logo. Finding these stickers attached and in great condition is difficult, as they show scratches and wear very easily.
This one has a sticker with a slight mis-alignment between the two printed colors. Mint condition, unused, but showing some wear from bumping around with other toys.
