When the kids were little they each had their own cassette player, this one and a Mickey Mouse WD 1030. I am not positive which one belonged to which kid but my oldest thinks this one was for the younger sibling. The players were pretty inexpensive and had very low level audio quality but they did what the needed to do which was to entertain. We had an assortment of tapes for them as well. As the kids got older and I introduced them to my Old Time Radio collection, much of which was on cassette, they had free access to those and each had their favorite shows with "Yours Truly, Johnny Dollar" coming in very high on that list.
