SD Gundam’s Worker Zaku in Straw Hat on a 1990 Playing Card

Worker Zaku SD Gundam Playing Card from Comic BomBom, February 1990

A Playing Card That Came Only With the Magazine

This item is a single playing card — specifically the 6 of clubs — produced as an exclusive free insert (furoku) for the February 1990 issue of Comic BomBom, the Kodansha children’s manga monthly that ran from 1981 to 2007. It was never sold on its own; only readers who bought that particular issue had a chance to receive it. The card belongs to what appears to be a full SD Gundam playing card set, with characters distributed across a standard deck, though the exact composition of the complete set has not been definitively confirmed.

Worker Zaku: The Zaku II Trades Its Weapons for a Pickaxe

The character depicted is Worker Zaku (Sagyoyo Zaku), a chibi-style reimagining of the MS-06 Zaku II from the original Mobile Suit Gundam television series, which first broadcast in Japan in 1979. In the SD Gundam line, the Zaku II — arguably the most recognizable enemy mobile suit in all of Gundam — was regularly recast in civilian settings rather than battlefield ones. Worker Zaku takes that concept to a vivid extreme: the card shows the character wearing a straw hat and carrying a pickaxe, with a white cloth marked “shoten” (shop) draped over one shoulder. The result reads as something between a farmer and a small-scale tradesperson — a comedic contrast with the Zaku’s origins as a mass-production war machine. This kind of affectionate, culturally grounded parody, dropping mecha characters into the textures of ordinary Japanese life, was one of SD Gundam’s defining creative moves and a significant part of why the line connected so broadly with children in the late 1980s.

SD Gundam at Its Height, Captured in Cardboard

SD Gundam — Super Deformed Gundam — emerged from Bandai’s gashapon capsule toy line beginning around the mid-1980s and grew into one of Japan’s most prominent character franchises by the end of the decade. By 1990, the property was running simultaneously across the BB Senshi plastic model series, OVA anime releases, video games, and a wide range of licensed merchandise. Comic BomBom was a natural home for it: the magazine regularly featured SD Gundam manga and goods coverage, and reader-exclusive bonus items were a well-established part of how the magazine built loyalty around popular franchises.

Japan’s furoku tradition — the practice of binding supplementary gifts directly into magazine issues — has deep roots in children’s and youth publishing. A compelling furoku gave readers a concrete reason to pick up a specific issue, and playing cards were a well-suited format: usable as a game, desirable as a character item, and flat enough to package without adding much bulk. Because these inserts never entered ordinary retail distribution and rarely circulated outside Japan, examples from this period are now found almost exclusively through Japanese sources. For collectors of Gundam-related goods or early Heisei character merchandise more broadly, furoku pieces like this sit in a category that the international market has had very little exposure to.
