The USS Atlanta and her sister ship USS Boston were early US "Steel Navy" era cruisers. They were both steam-powered and brig rigged. The 1/96th model on display at the Smithsonian Museum of US History in Washington, D.C. is gorgeous. I have a weakness for ships of this era and the Atlanta is among the most beautiful representations of a Steel Navy ship that I've yet seen. Unfortunately there is no commercially available model of this distinctive ship. So feast your eyes on these photos, or better yet check her out at the Smithsonian.
