The wonder of stamps, the catchy Canadarm name has stuck in my mind from when it was one of the stamps I received on a Canadian postcard and wondered what it was. I never thought about who invented it, like the cogs.

That's a wonderful set ... I always love to see a complete sheet, with full margins. By the way, in Italy, they prefer to credit Antonio Meucci with the invention of the telephone! Here's my post on Information Technology.
