I purchased the artwork from Minalima, https://minalima.com/product/the-weasley-family-clock/ https://minalima.com/product/the-weasley-family-clock/ and used that. It's officially licensed artwork.

Others have done custom artwork or made copies of official images (there are two variants that appear in the Harry Potter movies). I really liked this artwork, so that's what I did.
