Over the last 30-years or so, I've bought, traded, and sold numerous Gretsch guitars from the 50s & 60s. I have owned all the Jets, 6120s (with and w/o G brand), Roundups, White Falcons, Country Gents, and many others. One thing I found interesting is that many of these instruments still had most, or all of the original paperwork in their cases - something that I didn't see as much with Fenders & Gibsons. Also, most still had their original Gretsch strap. I even remember buying a couple mid to late 60s Country Gents that had their original plastic bags (with Gretsch logos). Any thoughts on why vintage Gretsch guitars seem to retain their tags more than other brands?
