Today amongst my shelves I rediscovered a pair of 6" apparently non
laminated metal disks.
They're self-evidently intended for use on a acoustic phonograph. There's
one sleeve. The instructions on it state "...Sing into the sound box loudly
and distinctly; if possible, use a megaphone. When you have finished, play
it over again and hear YOUR voice..." They have two different pre-printed
labels but their layout and color (royal blue background with gold
lettering) are very similar. One's "MARVEL VOICE". The other's
"REPEAT-A-VOICE". They are relatively heavy: seemingly heavier (for the
diameter) than if they were of the`'typical' uncoated aluminum recording
blank stock of greater size.
If any of you have historical information that you can provide (i.e. years
offered, etc.), then it'd be nice to learn more about them.
I've not yet attempted to play them.
