I LOVE your work! Incredible! This is exactly what i want to do in my basement, I might do a basketball court instead of hockey but wow! Thank you for sharing! You have incredible taste

Thank you so much!

The height is a little less than 8 feet and room is about 28 feet.

Hi @phalford, Here is a big batch of vintage Justice League wall art. From here it looks like they have many of the shots pictured here.

I think these are bigger and pricier than what you want. Google "Marvel Superhero wall art" and see some more choices!

It appears to be low-pile wall-to-wall carpet that's been cut and inlaid with the pattern of the sports court using different colors of the same style carpet - Any good retail carpet sales & installation company can accomplish a similar effect for you.

Sorry for the very delayed response but it is not carpet. It is rubber that is custom designed and poured on scene.
