I did find a wooden one but sadly it has been discontinued. However, I managed to find a decal over at the website Suzanne Nicholl Studio.
From the website: Retro Dive Girls are scanned from our hand painted wooden products, all the texture and detail is printed in the decal. You can order one or all three to fill up a wall. Each dive girl is about 47" from tip to toe, and about 13" wide. We can do custom sizes, or change the direction they face. $39.99
I'm off to measure.
