I had relatives that lived on Melrose and Washtenaw, next to the Grebe Shipyard, where the cousins and I would sneak into every so often. The Bally Pinball factory was there too, on the corner of Belmont and Washtenaw. When they moved from that facility, the cool juggling-man logo sign disappeared, which was mounted on the Belmont side facing west:



They used the same logo on their machines for a while. By chance, does anyone know where the sign ended up?

wayoutwardell, Bally was purchased by the seeburg corporation I believe back in the sixties. I'm not sure when seeburg went out of business but at least extends the trail for you.
