From September 1971: Marvel shows its mainstream appeal by landing the cover of ROLLING STONE MAGAZINE. With no TV or movie tie-in in sight to help seal the deal.
This was back in the days when the "magazine" was still published in a folded newspaper format on newsprint which is why this copy is a bit beat-up and doing its best to turn yellow.
But I'm not complaining as I found this issue in a stack of old copies from the same timeframe selling for £2 a pop. I couldn't quite believe my luck (and that the store hadn't seen the potential for jacking up the price on this particular edition). Hurrah for the Hulk.
