What I've noticed through these purchases is that many GPK sellers/traders seem to have substandard packaging and shipping standards. I've been getting a lot of singles sent loosely in envelopes and sets sent loosely in bubble wrap. One set arrived in ziplock bags. Having bought and sold baseball cards on Ebay for a number of years, I've become accustomed to carefully wrapped packages and envelopes for my cards. I usually consider leaving neutral, or even negative feedback for such carelessness, but this problem appears to be an epidemic within the GPK community.
"Anyhow", I like these BNS sets that came out in 2012-2013 through 3 different series. For some reason, Topps decided that they didn't want to continue with the All-New Series concept that last through 7 releases between 2003-2007. After 3 Flashback Series releases between 2010-2011, Topps started another theme they called the Brand-New Series. Like the Original Series releases between 1985-1988, Topps began using a continuous numbering method from each series to the next. BNS2 picks up numbering where BNS1 left off with #56a/b, and ends with #128a/b, where BNS3 picks up. The All-New Series renumbered each of the 7 releases beginning with card #1a/b. I don't know that one method is better than the other, but the concept is significant enough to point out.
What I like about the Brand-New Series is that it re-introduces characters from the Original Series and shows what they look like now. Other series have done this as well, but BNS had their own style of doing it. I've shown 5 pages from my BNS2 set below depicting 45 of the 146 cards from this set. BNS2 was the largest GPK release to date (unless you count the 3 Flashback sets of 160 cards), and the set size of BNS2 would not be matched again until 2015 Series 2: 30th Anniversary, consisting of 220 cards. Also, the BNS sets are much more affordable than the ANS sets.
