Pittsburg steelers game used helmet 1980s

Thin, very soft 50/50 cotton polyester by Garan, made in USA. Single stitch. One tiny near the bottom, some drain graphics, as shown in the photos. No stains, no other issues. Tag size XL, but fits much narrower than today's XL, more like somewhere between a M and L. Please note measurements to avoid returns: laid flat measures 20 across chest (armpit to armpit), 27.75 length (top of center of collar on back to bottom of shirt).
