Classic Philadelphia Eagles parka and pants worn by Hall of Famer Sid Gillman. Heavy duty bright green parka has Mighty Mac collar tag with "SG" written in black marker, Eagle logo patch on left breast. The pants are actually overall-style ski pants, only fitting for Philadelphia's cold winter Sundays. Bib of pants has Mighty Mac Skiwear, size 36, and washing instructions, and Gillman's initials are similarly written on the main tag. Not only was Gillman Philly's quarterback coach and advisor, but he was also the innovator widely credited with promoting the downfield pass, transforming the running-based sport to a closer version of what is seen today. As such, he is the only coach in history to be inducted into both the College and Pro Football Hall of Fame. Rock-solid provenance, comes with LOA from family member Tom Gillman as well as Photo-Matching & Grading LOA.
