Good catch on the White, Paul. The neckwear is quite different, as well as White's face and hair. After looking closer at the Spaldings, it appears they are from a slightly different angle, also. I've posted my Barnes CdV and it too appears slightly different than the image in the composite. His shoulders are more square in my CdV.
An additional point of interest that may have something to do with poses is where the Warren endorsement is located. Most have Warren as well as a Boston address on the front. My Barnes has Warren and Boston and Cambridgeport written on the reverse. This leads to the probability of the CdVs being issued on separate occasions.
