Yes, it is obvious! This mistake should not be made that easily. All the green Harvest labels are presumably stereo.
The first variation of labels is not from 1973, but from May 1986 reissue, despite the year of the release.
On 45worlds we make separate listings for Stereo and Quadraphonic records, so we should have two entries for Yugoslavia.
On the other entry, are the back cover images with LYEMI-73009 in Stereo and the LQEMI ones in Quad? The quad front covers are marked SQ at bottom right (also on label).
All the triangle labels show Quad, all the green ones show Stereo.
(I'm a bit puzzled - I only jumped in here to tidy up the label name!)
As a side project I've linked (hopefully) all countries' Harvest labels.
I'll look at moving the Stereo (green) labels tomorrow (unless another mod can help first...)
I'm confused that the Q appears prominently in all the cat#s, which I'd assume to refer to Quadrophonic...
Agreed. I've changed the label to just Harvest and deleted the dual label name. There is also "Jugoton / Harvest" which I will also change to just Harvest.
There's another entry for this - LQEMI 73009, which is listed as Quadrophonic, with lots of label images, some of which are marked Stereo and should probably be moved here.
