He put me to work running off press releases on the mimeograph and doing the mailings. He taught me his method for doing mailings that I have taught to assistants over the years. Run the envelopes through the Addressograph. Tri-fold about five press releases at a time and stack them up. Line up the envelopes with the flaps extended. Stuff them all. Then line up five envelopes at a time so you just see the glue (no self-stick yet). Take a damp paintbrush or sponge and paint the glue wet, then seal each envelope. When all the envelopes have been sealed, take a sheet of fifty stamps (always commemoratives - they attract attention), crease them at the perforations in both directions and divide into strips of 5. run each strip over a wet ceramic roller (no self-stick yet) and apply.
For lunch, he would take me to a coffee shop on Madison Avenue for a hamburger special: hamburger with fries, a little serving of coleslaw in a pleated paper cup, pickle slice, and a Coke. Even better, sometimes he'd have it delivered and we'd eat in the office. That and 25 cents was my compensation.
I long for those days.
