When BG sent me their older catalogs in 1993, along with samples, they gave me permission to use them for educational purposes. Otherwise, I would never use them.

I wish I had the same cooperation from some other folks.

EXAMPLE: A numismatist tabloild once went to my website and helped themselves to whatever they wished and published many rare pieces in my collection with values. I no longer have the pieces and I can't even use those pics even though the actual pieces were mine.

Your Pont is well taken...
