We may never know what the Riverside Foundry team was all about. We'll certainly never know all the players, who played what position, what their record was. One thing that we can likely posit is that the river that the Riverside is referencing is the Susquehanna. But that's about it. After all, we're not historians, just people who help you look cool. What we can tell you about this two-tone vintage jersey from the 50s, in good condition, is that it looks incredibly cool.
