Question mark
In the early 13th century, when the growth of communities of scholars (universities) in Paris and other major cities led to an expansion and streamlining of the book-production trade, punctuation was rationalized by assigning Alcuin's stroke-over-dot specifically to interrogatives; by this time the stroke was more sharply curved and can easily be recognized as the modern question mark.
? and the Mysterians
? and the Mysterians (also rendered Question Mark and the Mysterians) are an American garage rock band of Mexican origins from Bay City and Saginaw in Michigan who were initially active between 1962 and 1969. Much of the band's music consisted of electric organ-driven garage rock and an enigmatic image inspired by the science fiction film "The Mysterians". In addition, the band's sound was also marked by raw-resonating lead vocals of "?" (Question Mark, the stage name of Rudy Martínez), making Question Mark and the Mysterians one of the earliest groups whose musical style is described as punk rock. Through their music, the group was recognized as a template for similar musical acts to follow.
