The original Gerber baby has 91 reasons to celebrate.
Gerber celebrated Cook with a Facebook post Monday.
Cook was 4 months old when her iconic image became a sketch that is known around the world as the face of Gerber baby products.
The sketch was drawn by a family friend, Dorothy Hope Smith, in 1927 and entered into Gerber's contest in 1928. When the drawing won, Smith said she would finish it, but Gerber liked it in its original state.
Cook's identity was kept private until she joined the company for a 50th anniversary celebration in 1978.
Cook, originally from Tampa, is a retired English teacher and novelist.
