I'm pretty sure this was the sterio my grandparents had when I was a toddler. I distinctly remember the yellow and black and the big bold letters on the strap. With a quick google search I found it. I remember my grandparents having this plugged in outside of their red house. Back then they had a cement patio. They danced to Mexican polka music. They were so happy. They had a white metal patio set...and loved eating sliced watermelon on summer days.
I wouldn't say my family was super musical but I also wouldn't say my family wasn't at all. My grandpa had two guitars, an accordion, and a family piano. Pianos seemed to be a staple in my home... since forever.
