The publishing firm Humphrey Phelps (also known as Phelps, Humphrey) operated in New York City from the 1830s to the 1850s, at various times co-publishing work with Ensign & Thayer. They produced maps, prints and books, and are known for the “Phelps Guides” series of folding maps and wall maps for travelers, which Phelps began producing in 1838. Timothy and Edward Ensign were partners in a New York City lithography firm that worked in various associations and alignments with Humphrey Phelps, B.W. Thayer, the Kelloggs, Bridgman and Fanning between 1841 and 1861, producing prints and maps.
Condition: Generally very good, recently professionally conserved – old varnish layer removed, scattered small short tears and abrasions repaired, laid on linen, ribbon selvedge applied to sides. Lightly discolored with traces of old varnish and soft creases – but overall very good and quite attractive.
