the Columbia black label present on issues GL 500 to GL 525 was replaced by this maroon label with gold lettering.... it is still unclear until what issue this maroon label runs .. my thoughts were always until mid 650s but it appears that the early 700s or late 1955 when Columbia changed to its classic six eye label ... Billie Holiday's "Lady Day" (CL 637) came out on maroon label... this label corresponds to one of the more classic LP covers of all time..
