Thanks to Vanessa for this:
Please find a scan of a rather interesting piece of social history from 1866.
By the look of things, the houseboy needed a slip of paper which allowed him to leave his master's house after dark! Feel free to share on your site - the item belongs to me :)

It is interesting to note that the expiry date written in Chinese (Oct 25th) is different from that in English which states November 30th.
Expiry date
"30 Novemeber 1866" in Chinese calendar was the 24th day of the 10th month.
