Facing up to networking

Has anybody thought about putting a small portrait of themselves on their business card? Three reasons why came to mind: 1) so the recipient of your card wouldn’t have to rack their brains to remember what face was associated with this card after a networking meeting, 2) if you were arranging a meeting to, say, discuss a particular project or tout your new product, the other party would know who to look out for across a large hotel foyer or busy coffee shop, preventing the red carnation scenario, and 3) if someone wants to telephone or email you, having your image in front of them can help making that initial contact all that much easier…

Does anybody else have another reason for having your face smiling forth from your networking material?
