If you’re looking for a font of yesteryear, Showboat by David Rakowski might just be your type. Straight out of the gun slingin’/railroad buildin’ days, this font would be a perfect choice for a poster or printable design. I could see it also being a great fit for vintage clip art illustrations you can download or the Dover Publications you can pick up at your local bookstore! Also, you might want to share this one with your steampunk friends…I think they’d really fall in love with this one!
On a random, yet somewhat related sidenote, I’ve been on a showboat once: The General Jackson in Nashville, TN. I remember it had a show and dinner. I felt FANCY!
