A very rare version of the 1966 G-8 King Size Giftset in a yellow US only mail order box. Set contains K-1B Hoveringham Tipper, K-11 Fordson Tractor & Trailer, K-12 Wreck Truck and K-15 Merryweather Fire Engine. All models are excellent to near mint. These yellow boxes were used by mail order companys like Sears when ordering from their catalogs. The yellow outer box is in good condition, the inner blue plastic tray has some damage to it.
