Their are musical greeting cards.  They are greeting cards that have
chips glued to them which are triggered to play sound.    Has any
magazine advertiser ever tried to incorporate this into a campaign?  
Simply, has any magazine in the world ever carried a "sound-enabled
advertisement" which included one of these chips?  Magazines often
carry CD's or other crud that has to be expensive to produce so why
not a sound chip?

If this has been done, I'd like to know as much as possible about the
chip, where to get it, what they can do, etc.
