I love old vintage posters and I also love Americana art. These old examples were on Wikicommons--things in the public domain. I always say I want to use some of these old drawings as greeting cards. The one above was a July 4th poster from 1918. Even though World War I ended in 1918, it wasn't until November of that year. This poster was a celebration and also a positive message.
Have a happy and blessed Independence Day celebration!
