Is it the latest Apple expo shown here in Earl's Court? No, this is the golden age of the Monotype Empire in 1963. If you zoom into it you can see the Monotype Corporation stand and its subsidiary company, Pictorial Machinery Limited side by side covering 6,000 square feet. That's a lot of machinery. It made me laugh to see how smart all those printers and designers look down there.
