Actually quite a decent idea. Every year I try to get my regular opponent a historical based calendar for a Christmas gift, usually a WW-II or American Civil War based theme as we're both history nuts about these areas in particular. With the quality of artistry displayed on covers for modules or ASL Packs, I would certainly seriously consider purchasing such an item as I think so would others, ASLers or not, the way such items seem to be rapidly grabbed off local shelves. The outlay, I believe, may be rather minimal for the publisher being roughly a once a year commitment and the art would already have been within their inventory. Hmm, perhaps food for thought for MMP or others.You could probably make a decent calendar with the HASL modules with the historical month the action took place and perhaps some days highlighted for actual historical events.
HASL of the month calendar?
