Call sheets are distributed to cast and crew each day of filming to provide info on the entire day of filming - location, props etc. They are typically tossed out at the end of the day but sometimes they are kept and make it into the hands of collectors. This is a call sheet from Sanctuary Season 4 epsisode Sanctuary For None. Info on the sheet includes cast and crew names, map of shooting area and even a press release about Breakfast Television being onset for interviews. Cool little piece of TV history.
