Mexico "Onda Pop"
Pictured here are two albums in the "Onda Pop" series issued by Diana/Hallmark, whose logos are present on the covers.
The example on the left uses the cover art from Top of the Pops volume 4, the one on the right from volume 6 - but since they were advertised side-by-side on another Mexican LP, it is not unreasonable to suppose they were consecutive releases in Mexico.
If this is the case, they are probably - like other Mexican albums we know - compilations from more than one Top of the Pops LP. Furthermore, the songs are almost certainly given in Spanish on the front, making it extremely difficult to ascertain the track listings.
There is of course a possibility that these LPs do not contain Poppers material at all - but the presence of the Hallmark logo would be difficult to explain otherwise.
Since these are very early Top of the Pops covers, and since Mexico switched the series to its "La Ola Inglesa" series just after these came out, they could well be the only ones of their kind.
