Mercury Inner Sleeve Variations

A “Inner Sleeve”, a thin paper sleeve envelope which protects a vinyl record, had many advertisements or technical information printed on it. There were also many variations of the sleeves, and maybe few people don't know the whole variations of the sleeves that came with Mercury (and subsidiaries) records ever.

Of course I don't know either. Anyway, here are some of the variations.

Front	Back
A sleeve that came with SR-60737, a 1962 issue. This sleeve doesn't list other records up. But instead, a how-to for keeping records clean from the dust on the front, and an advertisement for Mercury's portable record players on the back.
