Georg Bolin "Tonbord" acoustic amplifier

This is truly a collectors item, very rare and unique invention from the famous luthier Georg Bolin in Sweden, a speaker system for amplifying acoustic guitar where the speaker is replaced by a real spruce top which is braced like a classical guitar, tiny dents in the edge of the wood but crack free, including hand written manual (inside the case under the inner lining) and original hardcase and original cables and 2pc pickups with the Bolin logo, including 2 stands made of wood (one smaller for tables and one larger for the floor).
