"Please find enclosed one pair of your overalls which I am sending you that the head of your fabric department may determine what is wrong. I purchased these from the Brayton Commercial Co of Wickenburg, Arizona, in the early part of 1917 and I have worn them every day except Sunday since that time and for some reason which I wish you would explain they have gone to pieces. I have worn nothing but Levi Strauss overalls for the past 30 years and this pair has not given me the service that I have got from some of your overalls in the past. I know that it is your aim to present a superior article on the market and consider it my duty to help you in any way I can. Please consider this and let me know if the fault is mine."
—Arizona miner Homer Campbell wrote a letter to the Levi Strauss company in 1920 asking why a pair of overalls he'd worn six days a week for three years straight had fallen apart. This is from a very interesting history of blue jeans the BBC has up—which reminds me of a lecture about global affairs I attended in college, given by a professor from India, who credited the invention of blue jeans as the single most important reason for United States' rise to solo superpower status in the 20th century. It also reminds me of the importance of blue jeans in pop music.
