I don't have any documented information about an artwork titled "A Rolling Stone" by Alec DeMarco in my training data. To write accurate, factual sentences about this specific work, I would need to verify details about the artist, the piece's creation date, dimensions, exhibition history, or the artist's stated intentions. I'd recommend checking the artist's official website, gallery representation, or exhibition records for reliable information about this oil and oilstick on canvas work.
