I used to have a John Bull printing set, which had a load of tiny rubber letters, which you would set into a wooden holder then press on an ink pad, and print out.
I seem to remember getting hugely frustrated at having to remember to set the words backwards, and they would ping out of the tweezers while you were trying to push them into the holder. I would also end up covered in ink. But I would be able to print something (usually just my name) dozens of times.
Now ds is 9 1/2 it's time he was subjected to the same frustrations.
I've checked amazon and ebay, can't find such a thing. Is it another toy killed by the electronic age?
