The Gibson Explorer
Gibson displayed a prototype guitar at the 1957 NAMM Show which was dubbed the Futura. It featured the body shape which would later be known as an Explorer, but with no controls and a "V"-shaped headstock.
Gibson produced very few Explorers during the 1958 run of the original korina wood model. Because production records have been lost and shipping records are unclear, it is not known exactly how many were made, but the original run total has been estimated to be no more than 50
