Any suggestions on how to photograph acrylic artwork?

I have a few pieces of acrylic artwork, fine art prints affixed to acrylic, & I'd like to photograph them for selling online. They're SO reflective, I find it difficult to get a good photograph.

Any suggestions from anyone having good luck photographing these reflective surfaces?

Thanks.

If you're photographing your own prints, tilt them enough to disrupt the glare and transform them to a rectangle in Photoshop.
But I'm wondering why you're asking so basic a question when you're selling acrylic prints that you made.
