1861-1880 Portfolio Creedmoor Rifle Range Match Original Harper's Engravings FL1

I counted 31 total engravings, could be give or take 1 or 2 either way. These are all original engravings from Harper's Magazine - the oldest I see is dated 1861, and I think the newest is 1878. These are all relating to rifle matches at the Creedmoor rifle range in Queens Long Island NY. Also has a couple pages of research. Contained in a portfolio measuring 14x19.5. Most of these are pretty good condition for the age, though I did see a couple with tears, and one that was taped on the back. See pics for condition.
