YOUR SCRAP . . . brought it down

Eject! Eject!

This poster urges people to collect and donate scrap metal for the war effort, and demonstrates how that scrap is used.  The artist is S. Broder.  U.S. Government Printing Office: 1942-O-486746. It is 28" x 20".  There is a very similar poster, with the same wording but with a different image and layout, also printed at about the same time.
