Page 27 shows the Gibson Jumbo B-45-12 twelve string amongst fallen autumn leaves. The Cherry sunburst finish really does stand out in this setting. The B-45-12 is described on page 33, and is one of two 12-string flat tops in this catalogue, the other being the B-25-12.
The B-45-12 was listed in the April 1966 price list, (zone 1) at $275, for either Cherry Sunburst or Natural finish.
