These particular shirts have been worn in service, and machine washed and dried, by machine repair technicians for two or three years by the time these scans were taken. Note the slight distorion in a few places due to fabric shrinkage. This could have been reduced or even prevented with proper laundering and ironing, but the owners prefer quick & easy care; they can always get a replacement shirt from their company anyway. Regardless, notice that the colours are still strong and the text clearly readable.
