This is a Under the Stars and Stripes paper doll set from about the turn of the century by Raphael Tuck featuring a patriotic theme (including an Uncle Sam outfit!). The others are uniforms for cavalry, infantry, and the navy. These uniforms are all in the style of what was pretty common by the end of the 19th century (American soldiers still wore blue), and the navy uniform in particular hadn't changed since the early part of the century.
Although the doll is a bit stiff (being at attention), this is a nice set and was auctioned off last year some time at Morphy's. I had downloaded so many interesting vintage paper dolls from that auction and have scarcely begun to post them! Anyway, the resolution on these isn't the greatest, but they are nevertheless nice to look at.
