Size 44, vintage 1960s racing crew jacket by Marquart's Sportswear, Buffalo, N. #33 was Dick Flaig who raced stock cars all over western New York back in the 1960s and 1970s. I saw him race every week at Holland Speedway, a NASCAR sanctioned track I believe.
Measures 24" across from underarm to underarm, 19" across the shoulders, 25" long sleeves and 26" long down the back. A few spots here and there but overall very nice condition. Nice piece of local racing history.
