Featured Artifact
The cornerstone
A flagship early issue presented as the visual signature of MurakamiSama—and a fitting entry point into the history of Murakami collecting.
Record details will be expanded as set information, grading data, provenance, and verified supporting sources are added.
Contribute researchResearch Spotlight
MurakamiSama separates what is documented from what is inferred, estimated, seller-described, or still under investigation.
Manufacturer figures, serial numbering, product configurations, and clearly labeled estimates.
When, where, and how cards and promotional issues entered the collecting world.
Grading totals recorded with the date checked, the company, and enough context to interpret them.
Known markings, distribution clues, provenance, and source documentation presented together.
The archive is continually refined as new evidence becomes available. Historical information may change when additional documentation is verified.
Hall of Grails
A curated home for the rare, culturally significant, and historically important Murakami collectibles collectors most want to understand.
No artificial countdown. No pressure to rotate. An artifact remains featured for as long as its story deserves the space.
