[78-L] "PERIOD MUSIC GUILD" LP label

[Thomas Stern]

Just noticed a couple of 10" LP releases on the PERIOD MUSIC GUILD label (PMG 2001, PMG 2003)
Trade mark as for PERIOD RECORDS.

There is also a MUSIC GUILD label, later issues from ABC records.

Is there any connection between the two labels (e.g. did Music Guild spin-off from Period, or ...) ???

How long did the PERIOD series last ????  Did Period evolve from Period Music Guild ????

Any information appreciated!

Thanks,  Thomas.
