[78-L] Verve Label Colours

[agp]

My turn for a label colour question. In particular can anyone fill in 
some time lines for the use of the black and silver Verve label 
versus the orange and yellow Verve label. I'm not sure what year 
Verve started up, was it maybe 1955? I know that in 1957 they used 
the black and silver version on the Ricky Nelson releases on 78, but 
there is also an orange and yellow version of his first release (I'm 
Walking V-10047). Both it and the second release, You're My One and 
Only Love V-10070 were on black and silver, I have nver seen a yelow 
and silver version of the second one, so I wonder if it exists. The 
anorak in me needs to know
