A 1972 Guild F-512 Blonde (serial #63088) 12 string acoutic guitar, with hard case. This example was owned and used by Chris Squire of Yes, at home, in the studio and likely on stage during the period.
As per a tour programme from 1973, Chris is noted as playing as "FY12 Blonde" which almost certainly describes this guitar, with the serial number looking indeed like it reads 'FY12' - when it should almost certainly read 'F5-12'. Provenance: consigned by the family of Chris Squire.
