Vintage Cowboys Long-sleeve T-Shirt. The iconic Dallas Cowboys, a professional American football team known for their dominance in the National Football League (NFL) as a member of the NFC East division. The Cowboys joined the NFL as an expansion team in 1960. The team's national following might best be represented by its NFL record of consecutive sell-outs. The Cowboys' streak of 190 consecutive sold-out regular and post-season games (home and away) began in 2002. The franchise has made it to the Super Bowl eight times, tying it with the Pittsburgh Steelers, Denver Broncos, and San Francisco 49ers for second-most Super Bowl appearances in history behind the New England Patriots' record 11 appearances. Their eight NFC championships are tied for most in the conference's history. The Cowboys are the only NFL team to record 20 straight winning seasons (from 1966 to 1985) during which they missed the playoffs only twice. This Long-sleeve T-Shirt is a must-have for any football fan.
