The Cardinals start a season-long celebration of Lou Brock on Tuesday with the unveiling of a new #STLisLou campaign that will help raise money for children with diabetes.

The club is encouraging fans to share videos, written messages and photographs about what Brock means to them by using #STLisLou hashtag.

Brock came over to the Cardinals in a trade with the Cubs back in 1964, so what better time to start the campaign then with the Cubs in attendance.

“Lou Brock is not only one of the greatest players to play for the Cardinals, he is also one of the nicest men to have ever worn the birds on the bat,” team president Bill DeWitt III said in a prepared statement. “Our fans selected Lou Brock as one of our Franchise Four, honoring him as being one of the most impactful players in Cardinals history, so we have no doubt that they will seize the opportunity to share their affection for Lou via social media this season.”
