Rapper Art Tribute at L.A. Home

Shaquille O'Neal made a video to help sell his L.A. area home -- but what it shows is the NBA star has honored 3 late rappers with some VERY cool art.

Of course, Shaq is a BIG rap nerd -- not only has he dropped albums, but he LOVES the genre and has a particular affinity for guys like Notorious B.I.G. and Tupac.

So, when he posted a brand new video tour of the Bell Canyon mansion he put on the market for $2.5 million ... the art on the walls caught our eye.

He's got two Biggie pieces along with a portrait of Pac and a newer image of Nipsey Hussle -- three great rappers who are all gone, but not forgotten.

If you're interested in the actual property, yeah -- it's pretty sick!!5 bedrooms, 4.5…
