The marketing team behind "Unsolved: The Murders of Tupac and The Notorious B.I.G" found a brilliant spot to promote the series ... right above Biggie's actual murder scene.

The late great Notorious B.I.G. was gunned down March 9, 1997 as he left L.A.'s Petersen Automotive Museum -- on the corner of South Fairfax & Wilshire. Now, a huge billboard right above that intersection shows his face with the tagline "20 Years. Still Unsolved."

The show premieres February 27.
