Here's a little peek at a typical mailart mailing from Ficus strangulensis. Notice that it's filled with items. This time, they are primarily artist trading cards. But Fike always sends a note as well. In this case, he commiserates with me about my recent burst pipes (now both of which are fixed) and asked me what "GNET" means on my eXmaSscard to him (well, Geof, Nancy, Erin, and Tim Huth).
