Slater de Brun follows through on his swing on this 2026 Pro Set Prospects baseball card, prominently marked “1/1 Pre-Production Proof.” A vivid red geometric foil design surrounds the batting image, with a contrasting patterned foil reverse.
A distinctive addition to a Slater de Brun collection. This is a pre-production proof rather than a standard pack-issued base card. No autograph is shown.
