12:51 PM PT -- Shareef just posted pictures of the nearly-finished tattoos ... and they feature Kobe's brand logo, a silhouette of Kobe mid-jump shot, the #8 and #24, Gianna's "Mamba" jersey and the words, "Mamba Mentality."
Shareef says the art will be getting background ink soon.
As we previously reported, Shaq's son became VERY close with the Bryants -- he basically viewed Kobe as an uncle.
Shareef has been deeply affected by their deaths and has been searching for ways to pay tribute to the Bryants. He's been posting a lot on social media. He went to the Bryant tribute at Staples Center. And now, he's inking their numbers on his leg.
Check out the pic ... you can see Gigi's #2 jersey she rocked for her Mamba Academy team. He also added Kobe's #8 and #24, the two numbers he wore with the Lakers.
