Dwyane Wade's Ex-Teammate Gifts Art Piece

Dwyane Wade ain't leaving Miami empty-handed ... 'cause his former teammate, Dorell Wright, just hooked him up with an awesome custom art piece to bid him farewell.

Wright -- who played with Wade for 6 years on the Heat -- hit up Michael Farhat of ART Mobb ... and commissioned him to make a one-of-a-kind art piece for his "big brother," D. Wade.

The vision? Farhat told us it's "Wade reflecting on the success and hard work he put in Miami and using that as motivation for Chicago."

The project -- which took 7 hours to complete -- was spray painted on a piece of plexiglass using handmade stencils ... and it's dope.
