When I was a kid my dad always had tons of sheets of Chartpak and Letraset lettering and rolls of colored tape-like line makers in varying widths. Also Exacto knives and ball-tipped embossing tools for rubbing the letters off the transfer paper. These were the tools of the analyst who had to make large charts without the benefit of computers. All were made by hand. I had such a fascination with the sheets of lettering that it made me a font nerd for life.
