paragraph_text: At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.
