One of the dying arts associated with comics is the letter column.
I've been going through plenty of back issues and it's shocking how many thoughtful responses there were to stories that probably weren't worth that much thought.
I reread a three parter in Batman Shadow of the Bat where rhe Floronic Man tried to get all of Gotham stoned. It was just a silly reefer madness psa, but many readers sent letters about their harrowing history with battling drug addiction.
Have you ever sent a letter to a title and get published? Do you have any memories of particular letter columns that stand out to you.
