Be on the lookout for a large amount of reproduction tintypes, ambrotypes, daguerreotypes and CDV's on the market.
This CDV exhibits the dot matrix pattern that modern printers employ. BE SURE to obtain a magnifying glass or loupe and look for this!!! With technology becoming better and better each day, it is getting harder to tell.
Also quite noticible, is the large, thick black border around the CDV. Additionally, the cardstock is quite lightweight, and is a bit of a rose color.
As the price on colored soldier images is skyrocketing, these copies are are proliferating. If in doubt, it is proably best to pass on by.
