Punch Die used on 1935 Auburn 851 Speedster

I've recently purchased an original punch die that was used on the 851 Speedster. Could anyone tell me what part of the car the die was used on? Thanks!

Your die is a printing block used to print a catolog or flier of replica Auburns in the 1970s. Randy Ema
