"We have also at this same park [Sportsman's Park] on the bleachers the sign that is 400 ft. long and 6 1/2 ft. high. We will show you this sign in the next edition of 'The Evidence.'

'Star Brand Shoes Are Better'"

Edited to add: Not sure if the 400 x 6 1/2 ft. reference means that the various Star Brand ads on the outfield wall were all part of the same sign?
