I believe today’s shirt comes from the 2011 season entry of the Bertrand Baguette (#30 RACB/Aspria Dallara/Honda/Firestone) entry of Rahal Letterman Lanigan Racing. His single entry with Rahal was the 500 where he qualified on the 5th row. Bertrand was leading with 3 to go when he had to pit for fuel. He ultimately finished 7th.
