Was that Jaejoong's face on the side of that bus?? Why, yes it is!  One of the ways Jaejoong is advertising his upcoming solo concert and fanmeeting is with ads which move all over the place.

CJeS, the agency working for JYJ, announced they have began their advertising campaign for Jaejoong's solo project, mini concert and fanmeeting.

The concert sold out in seconds and reportedly crashed the ticket website's servers.

"We put on advertisements on billboards all over Seoul, various websites, etc," said CJeS.
