Charles James Fox is depicted as a kind of person identified with these objects saying “Caira” in a political cartoon drawn by James Gillray. French materials inspired a design of these objects patented after Jacob W. Davis suggested the use of copper rivets. A name for one political group identified with these things became popular during the demonstration of 20 June, a protest demanding constitutional monarchy. A (*) lack of a type of these objects came to identify radical, lower-class (-5[1])supporters of the French (10[2])Revolution. A form of these objects (10[1])dyed blue, first manufactured in America in 1873, was inspired by a material named for the French city of Nîmes. For 10 points, name these objects that inspired the nickname of the Sans-culottes and which (10[1])were dyed blue by German immigrant Levi Strauss. ■END■
