Traveling Salesman - Expedition Base Set 137/147 Reverse Holo

This is a vintage Pokémon Trading Card Game card featuring the 'Traveling Salesman' Supporter trainer card from the Expedition Base Set, released circa 2002. Physically, it is a standard-sized card (approximately 2.5 by 3.5 inches) constructed of layered cardstock with a distinctive yellow border characteristic of the e-Reader era. The card features a 'Reverse Holofoil' finish, where the background and text area exhibit a rainbow-spectrum reflective sheen while the main character artwork remains matte. The artwork, illustrated by Ken Sugimori, depicts a salesman sitting with a large rucksack and a case of items including Poké Balls. A notable feature is the 'e-Reader' Dot Code striping along the left and bottom borders, intended for scanning with the Nintendo Game Boy Advance accessory. The card is marked with the ID 'B-43-#' and set number 137/147. Regarding condition, there is visible whitening and silvering along the top left corner and left edge, indicating surface wear. The centering appears slightly heavy toward the bottom and left. There is a noticeable fingerprint smudge on the foil surface, though no major creases are immediately visible from this angle. This card represents a transition period in the franchise's history where physical cards integrated with digital hardware.
