This is a previously-owned, youth-extra-large (YXL), green T-shirt with “1973 Firebird” printed on the front. It measures approximately 20 inches (from underarm seam to underarm seam) and is in very good condition for a used item (Savvy brand, 60% cotton / 40% polyester). The Pontiac Firebird was a pony car built by Pontiac and manufactured from 1967 until 2002. The Firebird was introduced in the same year as the Mercury Cougar, which also shared a platform with another well-known pony car, the Ford Mustang. The vehicles were, for the most part, powered by various V8 motors of different GM divisions. While primarily Pontiac-powered until 1982, Firebirds were built with several different engines from nearly every GM division. This shirt features the full hood bird logo, which returned in 1985.
