How often do you get a chance to visit a great 4 story Philadelphia mansion in one of the classiest sections of the city. The houses were built in the 1860s and Dr. A.S.W. Rosenbach lived here for over 25 years until he died in 1952. During that time, he and his brother bought, sold and collected classic books, original manuscripts and decorative arts much of which can be seen in the house, museum and library.
The house has been moderized in some ways with an elevator, rest rooms, etc, however, much of the classic style remains with some original furniture, great paintings (one room has paintings by famous American artist Thomas Sully of members of the Gratz family, who were well known in Philadelphia), original manuscripts such as James Joyce's Utysses and Lewis Carroll's Alice in Wonderland. In the vast library they also have the only original copy of Benjamin Franklin's Poor Richard's Almanac.
The mansion is visited by means of a guided tour with an excellent tour guide, then you are allowed in some of the galleries on your own, especially to see the work of Maurice Sendak, who gave the museum much of his work and some of his whimsical pictures are on display.
This place is a real find and a joy to visit. Entrance fee is $10. It is associated with other museums as part of the North American Reciprocal Museums, so membership in one of those museums allows for free entrance.
