A booklet is a card that opens like a book: two or more panels joined by a spine, with room for several signatures, large patches or whole plates. It is the format of a product's most expensive pieces, which is why it is almost always short-numbered, from 1/1 to /10.
It does not fit in a normal pack. It comes in its own wrapper or is the hit of the box.
What matters is inside. Value follows content: one signature, two, an event relic or a card's four plates.
It is catalogued as one card, with its number and run, even if twice the size.

The Metal Universe Printing Plate Booklets
Upper Deck issues the Metal Universe Champions printing plates in a booklet gathering the card's plates, as a reward for e-Pack achievements: three for Ilia Topuria, 2023 base #14 and Fresh Foundation #FF7, and 2024 Stellar Cartography #139. How they are obtained, with the achievement rules, is on the Ilia Topuria printing plates page.
How to read this list
Knockout print runs come from checklists with numbering; Topps' official sheets give odds, not runs.
