Can anyone help, I have the above set of Johnnie walker miniatures. The box contains 5 x 5cl miniatures 1 each of red,black and gold, and 1 cardhu and a johnnie walker liquor. The limited edition set was issued in 1994 to commemorate 500 years of whiskey making and comes in a black well illustrated presentation box. Has anyone got anymore info for me on it.I think it is rare, any idea of a value. Maybe willing to sell.
