An owner of a collection of original baseball art created by the late artist LeRoy Neiman is coming to an online auction. Over three decades, the celebrated sports artist created 129 baseballs for a friend, a bank marketing executive.

Most were done in colored magic marker and captured some of baseballs' greatest players. The collection will be offered in a Heritage Auctions online sale on May 16.

Among the highlights is a 1995 baseball of Mickey Mantle swinging a bat and it’s signed: “Mickey – There'll never be another.” It's estimated to bring $4,000.

A rare non-sports baseball in the collection has an image of Marilyn Monroe. It's signed by Joe DiMaggio and could bring $6,000.

Neiman died in 2012. He was known for evoking the kinetic energy of the world's biggest sporting events.
