Superballs!

Picked these up a toy vendor at a fair.  I am told they are 47mm superballs.   I don't believe they are made anymore.  I'm impressed with the detail of the scenes.  The one with the balloon shows a river, bridge, farm, roads, train, and possibly more. The scale (backgound compared to foreground balloon)  works well.  The same can be said about the sky diving scene.

I saw these when I went on line trying to find out who makes the ones above.  You can see more pictures on this person's flickr page:
