“Check out this new comic cover that @melissabenoist and I recreated. I do believe the recreation is from a Superman/Flash cover, but Supergirl makes everything look better. Don’t miss the crossover on March 28! @supergirlofficial @cwtheflash,” Grant wrote on his Instagram.
Grant guest stars as The Flash on Supergirl airing March 28th on CBS.
