From the December 11, 1963 issue of the Warren Times Mirror:
We often think of all-state teams as being meticulously thought-out and analyzed, but from Scott’s own admission, this wasn’t the case for the inaugural edition in 1939. Scott’s recollection depicts him being told – during the season’s final game – that he should pick his own team for the AP. Following discussions with football people at that Clearfield vs. Blythe Township game, Scott published a team that he acknowledges missed on one player: Pittston’s Charlie Trippi. Give Scott credit for selecting players from across the commonwealth, though; virtually all corners of the state are represented. Of course, Scott’s greatest accomplishment was beginning the AP All-State team in the first place. The team was selected every year through 2008.
As an aside: Blythe Township won the game 12-0. The school fielded a team until the end of the 1958 season and its high school students now attend Pottsville.
One more thing – the birthplace of the AP All-State team still stands, but it hasn’t hosted a high school football game since the mid-1970s. It now serves as the grandstand for the Clearfield County Fair:
