RCA-Victor LDS 6091 Living Stereo Shaded Dog Soria series LP. The Soria series was a special promotion of RCA recordings in DeLuxe boxed record albums with extensive illustrated booklets and scores under the direction of Mr. Dario and his wife Dorle Soria, both former heads of Angel Records in America. When the couple joined RCA Victor, about 1958, they organized the production of this superbly packaged series. The Soria albums can be identified in the listing by the prefix LDS in stereo versions.
