The articles behind these images below should give you a pretty good idea what sort of information is contained in BCN, at least let you get a taste. Of course there's lots of categories of memorabilia NOT even mentioned in this website but, hey, that's what BCN is for.
Oh, and a word on VIDEOS. You won't find them here. Most boxing films are copyrighted by Big Fights, Inc. and it is illegal to distribute copyrighted material without permission. Of course lots of BCN subscribers do trade videos but we don't allow advertising of videos which have been bootlegged from film and that's most of them.
These questions are answered in BCN:
what do you need to know to collect with confidence?
what is it worth?is it real?
how rare is it?
where can I buy it?
who do I trust?
