A photo taken at the Tate Modern in London shows a young child climbing on a multi-million dollar sculpture at the museum as his parents watch.
Stephanie Theodore took the photo and posted it on Twitter, saying, "Holy crap. Horrible kids, horrible parents."
She added, "I told the woman the the kids were using a $10mm art work as a toy, she told me I knew nothing abt kids. Obv she doesn't either."
Museum officials say they checked the sculpture and it was not damaged.
