First Time?

I've had these photos of John Manning for years now and have always admired the overall look of them.  I long suspected they were very early AMG photos of John, but never had any confirmation.  

Recently I came across these photos on some auction site.  They are much clearer images than the ones I have from this session.  The site put the date of these photos at 1955, which would make them very early photos of John.  Perhaps this was John's first session at AMG.
