TSR’s 1982 calendar is a fantastic time capsule of early, lesser known work by a stable of artists, including Larry Elmore (white dragon), Jim Holloway (crystal dragon), and Erol Otus (blue dragon).
They put some effort into this calendar. Each day has a bit of trivia related to the hobby: Writers, quotes, history, movies.
A 1982 calendar can be re-used in 2021 & 2027, as the days of the week will match up.
