A very attractive set but sadly anonymous. And there is definitely space for an issuer`s name. I'm wondering if anyone out there knows of an issuer who produced cards in a similar typeface or style so that we might get closer to the truth?
The date might be reached by working out the timeline of the invention of the electric guitar (I prefer the acoustic myself) and look, it mentions "The Shadows"... they were formed in 1958, but were then called "The Drifters".
By the way there is only one code because I can't find it in the original four volume set of trade indexes, but do let me know if you can.
Anyway the clue here referred to the fact that an electric guitar is often called an "Axe". It seems there is no real answer as to why, but according to the guys at Guitarist Next Door apparently a saxophone was also once known as an Axe.
