TMZ has learned Dwyane Wade just bought up space on a prominent Miami billboard ... to deliver the following "welcome" to his newest superstar teammates LeBron James and Chris Bosh.
FYI -- sources close to Wade tell TMZ the dude paid for the sign with his own cash.
No word if LeBron plans on buying up another billboard to send a thank you message.
