Have any of you 78rpm record collectors noticed that the top record on the stack pictured on the Triple-Play phonograph manual is a blue label Columbia record from about 1920-1922 vintage? This would be an acoustic 78 produced before the microphones & amplifiers entered the recording chain in early 1925. The label had gold lettering against a medium blue background, & was the label used just before Columbia's "flag" label, which had a pair of colorful flags on either side of a coppertone or bronze background. How neat for me to have noticed this!
