Questions
What is the difference between Hobby and Jumbo for this release?
Jumbo gives you eight autographs, eight base cards, and one on-card signature per box. The standard Hobby box contains four autographs, four base cards, and one on-card signature.
Are the highlighted young-star signatures guaranteed in every box?
No. Leaf states selected young-star signatures land at roughly three to four per case, making those names chase content rather than guaranteed box pulls.
Are the on-card signature and autograph subjects guaranteed to be specific players?
No. The format includes one on-card signature per box, but specific players, legends, prospects, autograph combinations, and insert themes vary by box.
