Action News was at the Please Touch Museum on Wednesday morning as artists painted parts of the 3,700 foot tall design.
The Phanatic was on hand, too.
The mural will go up next year at 24th and Walnut and will face the Schuylkill River and Schuylkill Expressway.
In the meantime, the Phillies want you to vote on who should be among those included in the design.
Just go to the website for the Phillies Mural and vote! You can also see a list of who is already included.
Voting ends next month.
The Philadelphia Mural Arts Program helped put together this design.
