I’ve think I’ve still got a couple of them buried in a storage tub. They’re from around 1974-1975. It’s a roughly 4” x 4” little booklet catalog on glossy paper with a photo of an artist on the front and text only on the inside. If the album had been certified ‘gold’, the RIAA logo appeared alongside the album title.I sent in for three of them in '67 and '68. Never showed up.
