When I was a tyke our family visited a relative who lived in Manhattan. While there we went to the Empire State Building. At the top, or near it, was a little booth where we could all cram in and make a little 45 rpm recording. As I recall, it was a greeting to our father, who wasn't with us at the time. We kept that darn thing for year, but I think it was lost in a subsequent move.
Still, it was so cool in the days before portable tape recorders and such.
