Sylvester Stallone may want to retire from acting and focus on painting full-time...
'cause one of his creations sold at an auction for AIDS research -- and made nearly half a million dollars. The actor and his family hit a gala in support of amfAR -- a prominent AIDS research foundation -- at The Wynn Hotel in Las Vegas last night and, Sly brought a painting with him ..
. a multicolored Stallone original. Check out the clip .
.. the auctioneer is asking if one of the warring bidders wants to one-up the current offer -- sitting at $410K!!! The bidder turns down the opportunity.
.. and, it sells to the other as people loudly applaud.
The camera quickly flashes to Stallone's face -- who looks so excited his work could raise a ton for a great cause. Check out the piece of art for yourself, called "Knocking Heads" ..
. full of vibrant greens, yellow and reds with faces deep in thought -- and a rendering of Sly as iconic character Rocky Balboa. If you don't know .
.. Stallone's painted for years, so this isn't a novel work -- but, it's still a heck of a lot for someone who doesn't paint for a full-on living.
Stallone received an award at the gala, from Tommy Hilfiger and his wife Dee . We're told the event went well and was incredibly profitable for the organization. BTW .
.. Sly was in a giving mood it seems -- 'cause he also auctioned off a spot in the next season of "Tulsa King" which went for another $300K.
Stallone may be a member of the "Expendables" ...
but, his charity contributions were indisposable..
