Alan Dart - Tortoise

I’m really after a Realistic tortoise pattern, the only good one I have found is alan dart from Irresistible Gifts. I tried to get a copy of ebay but the current going price is £36.00/ $56.00!!!
I wondered if anyone can help?

It’s also in the Noah’s Ark pamphlet.

If you use the right colors any of these would probably look great!

Thank you Jan
