I wish Topps wouldn't do this. I like the idea of a couple of unnannounced sub-sets every year, but usually they are numbered from 1 to 10. Serial Numbered #/10, originaly there was said to be 10 cards in this sub-set, but it's unlikely. May be only 5 or possibly just the 4 listed here
The best way to navigate this blog is to access the posts under the CHECKLISTS banner to the right. Opening one of these posts reveals a list of all the known cards for that particular series. You can then click on the card title to see the actual card. Some show the front and back of the cards while others only show the front.
2012 and 2013 are still empty as I've only just started to compile this blog and it's going to take a while to get the earlier checklists updated.
