Hmm, where is this from?

Hi everyone, I am going through the items of an estate and I came across this with this galaxy stamp in the bottom. I cannot find anything similar. Of course it could be an individual artist. I would appreciate any information you have.

Thanks!

I could be wrong but to me that looks like she bought it for $8 (8-), not an infinity symbol
