yellow stock copies with "Stereo" word are early 1970s repressings & often sold as originals
original 1960s pressings have the wider print & also narrower print but a vinyl press not styrene.
early 1970s repressing that is still being offered at original prices.
the differences are STEREO, 45RPM in a different font, different wording at the label base & the catalog number is a different font.
it's the equivalent of 1970s Okeh repressings with the small 45, of low value, if still collectable.
