Up until 98: No oil, maybe. No Olympia, definitely.
After 98: Oil, definitely. No Olympia, absolutely.
Currently: Soiled trunks selling, definitely. No dignity, unsurprisingly 
What makes you think they are "soiled?"

Nasser is all about the fans, so if some fans have fetishes for his used posing trunks he'll offer them. He told me on the phone, "If someone wants my posting trunks, so what? Sure, I'll sell them. Same goes for anything - weightlifting gloves, shirts, even pencils and pens."
Anyway, back to the topic, Nasser had no oil and was simply amazing as demonstrated in these incredible photos which put fear in the hearts of the jealous pumpkinheads
