Antique/Vintage small (2-3/4” x 4-1/4”x 3/4”) leather bound book with the title page labeled “Golden Key of Happiness or A Manual of Prayer” by the RT. Rev J. Milner, D.D. New Edition published by M.J. Knippel, 453 Main Street, Dubuque, Iowa. The black cover appears to be leather. It has a circular logo on the front with a figure that looks like either a Shepard or a Knight, and the words, “Quality by Kuppenheimer” embossed on the cover. This book is in one piece but in delicate condition, as the binding is coming apart from age and/or use. Great for a collector of church history, old books, or for sentimental or religious reasons. I would estimate it to be from the early 1900’s or over 100 years old by the dates listed inside as pictured.
