The prices of both those commodities were soaring in 1978. Things haven't changed that much. I could re-do this cartoon right now, leave off “and coffee”, and it would work very well.
This was my first sale to a major market. It was printed in 1957, but I remember making the sale in 1956.
Charles Preston was the man who, more than fifty years ago, convinced The Wall Street Journal to start printing a cartoon every day, and to this day he's still at the helm of their "Pepper . . . and Salt" feature.
I remember visiting Preston many times in his Lexington Avenue office on Wednesdays, which was "Looking Day" for the local cartoonists. Unfortunately, I don't have a photo of the young, dashing Charles Preston of those days, but I have this photo of him and myself at the 50th Anniversary celebration/exhibit, which was held at the World Financial Center in 1999.
That's Preston on the left, me on the right.
