EMI's Columbia label, not Harvest.

EMI’s Columbia Graphophone Company. Pink Floyd’s debut came out on Columbia in 1967, before EMI created the Harvest imprint later that year.

The band moved to Harvest for their second album A Saucerful of Secrets, but Piper is pure Columbia. Records from that era usually have a black label with silver text and “Columbia” in big letters at the top.

If you’re hunting for an original pressing, look for that Columbia label. Harvest reissues exist, but the first run was all Columbia.
