Derek Curiel Vintage Onyx Extended Auto Master Set Baseball Cards

The listing

Offered here is a complete Ultra Extremely Rare 4‑card rainbow true master set of Derek Curiel autographed baseball cards from the Onyx Vintage Extended release. Each card features a distinct ink‑color signature — black, red, green, and blue — creating a visually striking and ultra‑rare full‑spectrum autograph run. All four cards were signed directly by Curiel, each with consistent pen pressure and placement, confirming authentic session‑signed pieces. These are not mass‑produced parallels — they represent a true ink‑variation master set, impossible to replicate and seldom seen together. There are only five sets Globally. Here is one of them.
