Oodles of Doodles LXV

The instruments above come to our doodle-fest courtesy of Marjorie Meinert At The Lowrey Organ-Sitting Pretty (RCA Victor LSP-2168, 1960). I don't know why everyone was so into the organ back then. I guess it was the sound of something new and different. But how different was it? I know it was smaller than the big steam organs found in theatres and churches, but still, was it really that different? I suppose so, based on the number of organ oriented LPs out there. There is a small signature down in the lower right on this doodle. It says Jo Grey II, but Google isn't returning any hits on that. (Just for the record, this LP has a preprinted 317X notice, but no slogan above the RCA Victor logo.)
