I'm impressed by this collection, especially as calendars are so often written on or simply thrown away at the end of the year! As with a lot of 'ephemera' this is what makes them even more valuable items.
davem has a couple of the really old calendars, still with their envelopes.
One of these days I'll get round to doing a scan of the Hobbit playbill I have from the production in Liverpool in the 80s... I found it under my bed! The playbill, not the production...
