Reader @Jordanfabian passes along the above ad for the Capitals’ inaugural season. It appeared in a 1974 Redskins game program.

If you think football season tickets are rough, get ready for NHL hockey.
Redskins tickets are hard to come by.
Hockey’s gonna be worse.
We’ve seen it happenin’ with other new NHL teams in Atlanta and Philadelphia (Just try to get a season ticket today).
And it’s gonna happen here.
Get in on the first season of a brash, scrappy new team.
Watch things get rough on the ice, not at the box office.

The Caps finished the 1974-75 season 8–67–5, and the 1975-76 season 11–59–10. I’m guessing it took a while for things to get rough in the box office.
