You may soon encounter a billboard with 1,000 happy faces smiling down at you.

On Sunday, many of them sat down and had their pictures taken.

They were attending a fundraiser organized by the group One Thousand Happy Faces at the Victor Hotel.

The event had two goals. The first: To raise money to benefit Children's Memorial Hospital.

And for the second, photographers took hundreds of pictures.

Photos of those happy faces will appear on a large billboard that will go up here in Chicago.
