These are very rare survivors. They come from a small selection of vintage Olympics paraphernalia which I have on offer in my Iconic Edinburgh online store.
These are two published reports for the Commonwealth Games held in Edinburgh in 1970 at Meadowbank Stadium (now sadly demolished to make houses!)
The books / magazines both have soft covers are of a matching design. They were published by the Athletic Arena: The International Track and Field Magazine.
They each have about 30 pages and discuss results and have photographs etc from the games.
The reports measure 28 x 21.5 cm. The two magazines are on offer here.
