Lou Williams decided to honor Kobe Bryant and his daughter, Gianna, by getting a HUGE mural in his man cave at his Atlanta home this week .. and it's pretty amazing!
TMZ Sports has learned the Los Angeles Clippers guard hit up his good friend and tattoo artist Fennell "InkByKali" Cunningham for the Mamba and Mambacita mural.
We're told because Lou and Kobe were real close, InkByKali had to make sure the mural was perfect ... so he hit up another artist, Tay Hill, to help out.
