Straight from the Cold War, here's a vintage postcard from the Soviet Union with a great message that transcends ideologies and generations.
The card shows a young boy who is doing some woodworking. He is surrounded by images of boats, an airplane, a rocket ship, birdhouse and a futuristic helicopter.

Here's the back of the postcard, which I have not attempted to translate, because Russian cursive is not my specialty.
Here's a closer look at the postcard publisher's logo and that groovy helicopter.
