Charlie Murphy Took This Last Selfie With Fan Weeks Before Death (PHOTO)

(TMZ) -- Charlie Murphy was gracious to the end ... taking time for a fan weeks before his death.

The pic was snapped around March 24 at Dallas/Fort Worth International Airport. Mickael Brodie asked Charlie for a pic before boarding a plane for Newark, and Charlie was more than accommodating.

Mickael says Charlie was super nice.

Turns out Charlie was in and out of the hospital, undergoing chemo but kept his illness secret to almost everyone.

TMZ broke the story ... Charlie died Wednesday after battling leukemia. See the selfie below.
