Shorpy put up a picture of downtown Philly taken in 1912.
An interesting detail was Snellenburg's, which had been around for over forty years at that point, had a sign/scoreboard
with baseball scores, on the storefront, sponsored by the Inquirer
newspaper
I would think that posting the results would kill sales of the paper but it probably stirred up interest so people would buy the paper
to read the inning by inning story of the games. Or maybe the scores would hold people over until the Inquirer came out in the morning
instead of buying the competing Evening Bulletin.
1912 didn't provide a lot of options to the papers.
