To finish out a week of printable props, a cheque book.
Since we were looking at the British Banking System a few days ago.... why don't I give you Bank of London chequebook to print out and make. This should make it easier on players and keepers who don't want to keep a whole lot of 'money' on hand, but do want to keep track of how much their characters have spent over the course of the campaign (especially for large purchases).
As a side note, I'd like to recommend The HPLHS Prop Documents CD-ROM. They have an excellent printable Arkham Bank Checkbook and various Arkham Bank paperwork (along with a host of other props).
