I have a foot-high stack of 1940-1950's "Etude" magazines with lots of
fun musical pictures and ads in them. I've scanned in three, and they
are now on the MMD picture page at:

    http://mmd.foxtail.com/Pictures/

They are as follows:

1)  Alcoa Aluminum ad showing a stereotypical 1950's ad touting an
aluminum piano that weighs 100 pounds less than a regular piano.

2)  The cover of one 1949 issue, the year television was first widely
available to consumers, shows Paul Whiteman "seeing television for the
first time".  The feature article is an interview with him about how
television will influence music.

3)  An ad for a wire recorder aimed at music teachers. A few pages
later, there's an ad for a reel-to-reel tape recorder stating that tape
is superior to wire because the sound does not bleed to other parts of
the medium (crossover due to unwanted magnetic induction?).

They're fun to look at, and I'll submit more to the MMD editors as they
are appropriate.
