BIDDEFORD, ME (WGME/CNN) - It's not your typical car window advertisement.
Rick Stilphen has been on kidney dialysis for five years, and has hard a time finding a match.
His blood type is "B" and it's rare, so he stuck some decals on his car hoping someone will see and help him.
Stilphen said since he put his information on Facebook he's had several people contact him. Even if they're not a match, he likes the responses because those people might know someone who is.
"It's a numbers game," Stilphen said. "As long as they're trying, they might be connected with someone else along the way."
Stilphen has been on a transplant waiting list for three years.
