Marylin Monroe on the cover of Look

Might be cool to recreate Andy Warhol's Marilyn Monroe Diptych on a t-shirt using that image. Would probably be a copyright nightmare, though. @Pantone4515
That is a rabbit hole of a question. Can't even begin to summarize it here. Warhol himself was found to have infringed on a few copyrights (he painted Prince without his consent) and I think his foundation was also found liable for profiting from licensing works for other living artists even tho they didn't own the rights to the works. It was in the courts for a very long time.

However, it would be fine (I think) to "Warholize" the photo of Marylin in the GT merch provided the photo has entered the public domain.

Very good idea, actually.
