10:19 AM PT -- 9/11 -- The mural is so cool ... Kelly himself had to check it out in person -- and he even brought his family!!!
The L.A. Dodgers reliever -- who just came off the injured list but now needs to serve his 5-game suspension -- took some time see the massive artwork Thursday ... and it's pretty clear Kelly is enamored with the piece.
Check out the photos his wife posted ... everyone's loving being there -- and they even recreated the famous pouty face at the scene!!
"Today was special because our fam got to see THE mural of our guy!" Joe's wife said. "[Jones Never] is a stud of an artist (and fellow UCR Highlander) who literally transformed this wall into pouty-face gold 🔥🔥🔥"
Forget how savagely Joe Kelly trolled the Houston Astros back in July??
No worries ... the Dodgers pitcher's incredible pouty face jab has now been immortalized with a mural in Los Angeles -- AND IT'S 16 FEET OF INCREDIBLE!!!
Jonas Never-- one of the most famous street artists in the country -- painted the piece this week on a barbershop near Dodgers Stadium ... and it was completed just in time for the 'Stros-Dodgers series this weekend.
