One of a series of Spanish represses/rereleases pushed out to coincide with the 1978 world tour. You can usually distinguish the earlier issues from the later ones in this series by the fact that different colours were used on the back sleeves. However, this one is different as both 1973 and 1978 issues have a blue reverse sleeve making it hard to spot the difference. However, 1973 issue uses a different typeface to the '78 reissues (scan of 1st centre added is from '73, latter scan is from '78 for comparison purposes).
