Pittsburgh's bicentennial year was in 1958. I know this because the 250th anniversary was celebrated in 2008. Sad but true. I love that Pittsburgh is an older city. I think that's where it gets a lot of its charm. The history is rich. But I guess, compared to most European cities, Pittsburgh is still fairly young.
This postcard in particular is about double the standard size, and was a little beat up, but thought was worth having, if for nothing else, to simply have yet another Pittsburgh postcard. :)
There's still been so much growth since then, too.
