For those interested in variants, while searching for a Black Series 6-Inch 68: Tobias Beckett figure with a decent face paint application to photograph, I noticed that Hasbro has changed up the blue color paint used on the small portion of his undershirt that is shown. Figures with a early date stamp of 81411 had a bright shiny blue color undershirt like Hasbro's prototype photos had, and figures with date stamp 81561 and above had a flat navy blue colored undershirt. I was able to find multiples of each, so they are out there.

Above is a comparison photo, bright shiny blue on left and flat nave blue on the right. My studio lights may have drowned out the colors a bit, but it is very noticeable in hand.
