I'm the author of the 2008 book "Guitar Picks of Rock & Roll". I've also collected vintage guitar picks, on and off, over the past few decades. My dear friend, Joe Macey (RIP) once bought my vintage pick collection and I have had the honor of buying his collection before his passing (which was way too early). I do not profess to know all that Joe did, but I have been recording all the pick knowledge he has passed on to me over the last 12 years or so. I now feel like the curator of the Joe Macey collection and it saddens me to not be able to enjoy it all with him, but I hope you enjoy it. I will try to submit additional photos in the near future. Cheers, Brian
