1975 Johnny Bench Game Jersey - is this OK?

[diamondicons]

I was doing some research on Reds tagging and came across something I have never seen and is inconsistent with other 1975 Game Used Reds jerseys that I have examples of. Item in question is a 1975 Johnny Bench jersey that sold in auction last year for $14,220.00. Everything appears correct on jersey. However, if you look closely at the wash instructions on the Rawlings Label it states..."WASH IN LUKE WARM WATER". Instruction are also specific on water temp. I've looked at several other non-Reds jerseys and have been unable to find another Rawlings label with these instructions. Below is the Bench Label (warm water) and a Gary Nolan Label (cold water)...both from the 75 season. Anyone on the forum have thoughts on how this could have occurred. Does it affect the authenticity of the jersey. Mike
