Sent to the address below before he was traded to the Houston Rockets. Unsure where you would send to him now. Likely got mine in time for one last fan mail round up as he left Washington.

Sent 1 TC on 11/2/20 and came back signed 12/30/20. Thank you Mr. Wall. One of my all-time favorite UK players.
