Ibanez is Flexible
Ah, the flexidisc - promotional media of the pre-youtube/mp3 generation. This one appears, based on it's somewhat jagged/perforated edge, to likely have been bound in a magazine. Here the primary demo is the Ibanez Digital Reverb, with a promo of the Ibanez Midi Guitar System sneaking in as well.
This flexi has a little crease in it - you can thank my high-pass filter for the survival of your woofers.
