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.

Note: The innersleeves presented here are “generic” ones: custom innersleeves designed for specific albums (such as SRM-1-697 and SR-61024) are not included here.
