Invitations, relocation, get well and retiral caricatures for friends and family and sometimes for the great and the good. When I worked in an office I used to do leaving cards for those who moved on if asked. And because I cannot remember names to save myself I had a caricature of every Countryside Ranger in Scotland at one point. They came in batches for training, each year, in blocks of a week or two spread throughout the year and it was the only way I could retain all their names. The Scottish Countryside Rangers Association has them all now.
