While I am on the subject of awesome teenagers from the 1970s I happened upon the website for photographer Joseph Szabo. (The url is photosofteenagers.com he must have been a serious internet pioneer to score that one) 
This image must be his most famous at least among grunge fans who know it as the cover of the Dinosaur Jr. Green Mind album.
His other photos are also very amazing.
He seems to have several books of his photos Almost Grown, Teenager, Jones Beach and Rolling Stones Fans but they seem to be out of print. I am going to keep an out for them on ebay.
