Due to my mom finding this EXACT model of toy keyboard multiple times at flea markets (and then giving them to me) this early 2000's toy ended up embedding itself in the depths of my mind.
I do know WHO created it! "Hello Modern Toys" or "hmtoys" from Hong Kong/Mainland China.
But how the HELL where people buying these toys? The packaging seems to be lost to the sands of time (or probably land fills, to be more correct) and I still have ZERO clue what retailers stocked these.
Perhaps the hmp139 was sold through junk mail catalogs ("Heartland America"). God, I wish I knew!
Do you remember anything about where it was bought/sold and/or the packaging?
