Just in time for baseball season, I found a blast from the past at Party Source.

Old Style. What used to be the official beer of the Chicago Cubs and Wrigley Field.*
One of the predominant memories of spending many afternoons at Wrigley Field was the
beer vendors shouting, “Aye! Old Style ‘ere!” Old Style will always be linked to the
games I was luck enough to take in my baseball Mecca, Wrigley Field.

*That may or may not be true. But it’s how I remember it.
