Since the Zoltan craze started for the Pirates last year Topps has had a few releases showing the Zoltan symbol being used.
The first was Josh Harrison's Topps card from last year.
While it is exciting to remember Josh's walkoff, it's incredibly depressing to remember that he had no idea how to make a Z. No Mr. Harrison, that is an S. Not a Z. This is why you had to go back and forth between the minors and majors last year. Learn the symbol, then you can come back up and play with the big boys.

The first card from this year to feature the Z is a Topps Museum Andrew McCutchen jumbo jersey relic. The same image of Cutch is also shared on a booklet with Starling Marte from the Museum collection. So far no other releases have shown the "Z"

The 3rd card that I became aware of using the Z was the Pirates Team Set version of Travis Snider.
