The artist's name is signed in the image on the left side and the logo of The Advertising Council Public Service Project appears on the right side of the image. The lower margin indicates a 1951 publication date making this a Korean War era piece. This poster is printed one side only on lightweight cardboard in the format most commonly used for overhead advertising on streetcars, buses and passenger trains.
The upper and lower corners on the right side are a bit bumped and there is a small chip off the tip of the lower right hand corner. The colors are strong and overall condition is very good for this rare vintage original. If you have questions about how to pay for this item please let me know.
