Brandon has obtained such an extensive Autograph collection Over the last 20 years by obtaining the drivers autographs in-person and working with various drivers and teams at many NASCAR tracks and special autograph events. His collected autographs range from drivers in the 1950's to current Super Star drivers and Rookies. Brandon has authored articles published in Autograph Collector magazine that focuses on signature studies and is currently writing a book regarding the NASCAR Autograph hobby and it's history.

Brandon's extensive research and consulting work with other industry experts make his opinion the most sought after in the hobby when in comes to NASCAR signatures. Brandon is the ONLY recognized NASCAR Autograph expert in the United States of America and is a member of Global Authentics LLC's Authentication Team. Brandon also works VERY close with ebay's fraud division on a daily basis. With Brandon's help, HUNDREDS of NASCAR forgeries have been removed from the marketplace each year.

Brandon's goal in the hobby is to simply help educate the buyers and to remove as many forgeries as possible within the marketplace. Brandon continuously render's his opinion for to ANY customer who seeks his assistance he enjoy's the personal contact with customers which allows him to ensure that the customer has a clear understanding of the item in question. Brandon has time and again shown that authentication should be less about making money and more about educating buyers in hopes that they will not be a victim of a forgery.

Brandon's current opinion is that NASCAR autograph forgeries are on the rise faster than ANY other section of the hobby. This is mirrored by NASCAR's international growth and continuous gaining of popularity. The huge DEMAND of NASCAR driver's autographs can not meet up with the supply. Though it may be that EVERY NASCAR driver signs HUNDREDS of autographs a week during the race season, the supply can not be met in the market due to the high number of COLLECTOR'S who keep the autographs out of the commercial system.
