Caricatures make a wonderful and powerful attraction to any trade booth. People love to see Gerry doing caricatures. She usually has long lines waiting to get theirs done. By hiring her, you are guaranteeing traffic to your site.
While those people wait for a caricature, you can be chatting with them, and hopefully make a sale or possible repeat call.
