“Due to the start of offseason construction, we will need to fence in these beautiful postseason memorials and remove the artwork from all areas of the ballpark,” president of business operations Crane Kenney wrote in a letter to fans, according to the Chicago Tribune. “While we hate to remove these cherished messages, chalk is a fleeting medium. To preserve these images, we will continue to photograph the outfield bleacher walls so we may share these postseason wall messages publicly in the future.”
Fans are allowed to leave messages on the wall until 5 p.m. Tuesday, at which point the drawings will be photographed for preservation.
Kenney added that the team hopes drawing on the walls “will become a Wrigley Field postseason tradition.”
