USA: Will you supply eyes for the Navy?

Today I got four postcards: one from the USA, one from Australia, one from France and one from Germany.

The card from the USA shows the World War I poster "Will you supply eyes for the Navy?" by Gordon Grant. The poster calls on the people to donate their binoculars and spy-glasses. For every one they got 1$ and if possible they got them back after the war.

The card was sent from the Postcrossing Meet-up in Needham, Massachusetts.

Thank You very much Christa!
