Panini Instant last week unveiled the first wave of unique new memorabilia autograph cards featuring pieces of signed pylons and basketballs honoring the stacked 2018 NFL and NBA Draft Classes. 2018 Panini Instant Pylon Signatures kicked things off last week as more than 30 top rookies were listed throughout the week on limited-edition cards featuring base versions numbered to 10 and Black 1/1s. Although many of the Pylon Signatures cards sold out immediately upon release, a small number of key cards remain available.
