2LP

Double LP series by Polydor. This is not for every double-LP, nor everything that says "2LP" on it, but rather just those items on Polydor/Phonogram-related labels and bearing Polydor's 2LP logo. It sometimes appears with the Double Special Series logo.

This is a series, not a label. Only add this to the "Series" field, together with the actual label of the release.
