Most of these are from the Eddystone, Chester, Pennsylvania, known for their mourning prints. Many of the conversationals of the 1880s and 1890s were on dark grounds as darker colors were common for the era. Queen Victoria, in mourning for her dear husband Albert (died 1861 from typhoid fever) and Empress Eugenie in mourning for Napolean III (died 1873) and her son (died 1879) set the standard. Queen Victoria remained in 'widows weeds' for the rest of her life. The prints below would be considered more appropriately as 'half-mourning' when solid black gave way to greys and purples.
Yes, you have seen some of these before.....but Halloween is on the way and I couldn't resist. I wonder if they were printed for Halloween... Sorry, didn't find any black cats or skulls in my collections of 19th Century conversationals
