It is not a modern re-print. The print will be mailed in a mailing tube. A chromolithograph is a lithographic process patented by Godefroy Engelmann in 1837. For every color present in the image, a sepearte printing stone or plate had to be inked.
The colors were built up in transparent layers. (Unlike photomechanical processes which use precise dots of only three colors red-blue-yellow and black and to get the other colors the dots are put close together). The way to distinguish a chromolithograph from a later color printing technique is to look at it with a magnifying glass. If it breaks up into color "blops" it is a chromo, if it breaks up into perfect rows of dots under magnification it is a photomechanical process. Chromolithography was used mainly between 1855 to 1905. The item "1882 Antique Map Bird's-Eye View of Cairo Egypt with Pyramids & Hot Air Balloon" is in sale since Wednesday, July 18, 2018.
