Pair of 1865 dated Union patriotic envelopes published by Charles Magnus. Both covers are a deep lavender color with a gilded imprint, one in silver and one in gold. Each have an eagle vignette with the caption "U.S. Armies Operating against Richmond, Va." with places to write in the Company, Regiment, Brigade, Division and Army Corps. The silver printed cover is quite attractive, the gold imprinted cover has oxidized somewhat. Both have the 1865 Magnus, New York imprint at the bottom. These are quite rare to find!
