Here is a composition I did using a photo of Sergio with a photo of One Mile Beach at Forster that I took. I added the drop shadow which was time consuming.
Wayne Gallasch took the photo of Sergio. I contacted him online and asked if he had the negative. No, he said Wayne Bennett's wife had the negatives and doesn't reply to his emails.
In my opinion the physique in this photo is probably the best ever developed by anyone. Great size but also superb shape and proportions.
