Design: A pie-shaped format, similar in concept to the well-known Telefunken layout, tightly designed and well printed. 'Cuatro Llaneros' refers to the llanero, a Venezuelan sheep-herder, whose genre of folk music is played on an instrument called the cuatro, a four-stringed instrument similar to the ukelele.
History: Unknown (have info? Please send to firstname.lastname@example.org). Evidently catering to the large Spanish-speaking ethnic group in New York (and possibly Boston, hence 'Bost'?). Label scan courtesy of collector Jean Theriault of Canada.
