I sometimes print business card sized or slightly larger pieces using either Micro$oft Word or Publisher, cut them out and attach them tp the back of the backing board with double-sided tape. I have a postage stamp sized self portrait behind my Bronica and contact information as a generic template. I then add the title and usually a brief description of what the photo is, and the date taken. (I do that all on the computer, as my writing is abysmal!) I do date and sign prints on the back in pencil.

Making such stuff is so easy I find a tendency to keep redesigning it!
