[78-L] HOLLYWOOD Label c.1930 by Columbia - For Radio Broadcast Only

[78records at cdbpdx.com]

Just came home with a small collection of interesting records and found a few labels I haven't seen before.  One is a 10 inch HOLLYWOOD label 78 rpm from 1930 produced by Columbia records labeld 'Not For Sale and 'For Radio Broadcast Only'.  It is a good quality record, equal to Columbias of the period, I think.

There is a picture of a 12 inch HOLLYWOOD label from 1935 in the Collectors Guide to Victor Records, but it is very different, though I suspect they may be related.  
 
Was this a cross between a radio transcription and a DJ Sample record?  Is it pretty rare?  Any other comments?
 
Thanks!  CDB
