One of the things I do is use my business cards anytime I write something or have a spectator write something.
Another good piece of advice that I use now, which came form a good friend of mine named Danny Ray ( who is also a working pro ). . .ok. Hold up. Actually his wife shared it with me, sorry Danny
. Their idea was to sign my website, instead of my name, so when ever I scribble my signature it looks like this, robertmichaels.net
When I do my signed torn and restored card or have a spectator sign something, I also sign it with my website. My website has a simple close-up demo on it that I did years ago with a cheesy camera and it gets me gigs
During a stage performance I give out at least 5 biz cards that have an emotional connection attached to them, because the spectator wrote something down that became a miracle. This way I'm not just giving them a card, its a memory to them that they will hold on too.
