Topps just announced that anyone that has any of the SP Sparkle variation cards from 2014 Topps Series 1, should start ripping them open to find exclusive 1-of-1 parallels. These are similar to the 1-of-1's that were included in the box tops of 2013 Topps Allen & Ginter! These special 1-of-1's are actually smaller than the early 90's Topps micro cards. I think they are calling them Nano-fractors and they are actually colored shit brown.
I have also heard reports that you can find the SP sparkle variations by their smell. It smells eerily similar to the Sparkles from 2011, which in turn actually smell like shitty baby diapers and Desitin.
