Here's a link to a new web site that has some good old books, old photos, and some
other Pit Bull stuff --
http://www.apbtbooks.com/index.html
There are some nice old photos and books that are hard to find, especially the old Pete Sparks reprinted books.
I have most of the same books in my own collection and those old reprints done by Pete Sparks years ago are much better quality than the new paper back copies from the UK.
And I like that Heinzl harness, it looks like a good design.
