The only logo things that I have found that I use, and the first two would likely not be appropriate for cc, are a neoprene wine tote for a bottle of wine, a matching cork top, and (this could work) a small portable folding/collapsible umbrella. DH Has brought home or received in the mail a gazillion thermal water bottles/mugs and these days most of them are high-quality (yeti).
Maybe someone would buy one of those license plate holders that is framed around a rear license plate?
