The July Monarchy (1830-1848) is a very important period in the history of popular visual culture in France. This period is characterized by the following three points : (1) development of mass printing industry, and proliferation of block prints produced by new techniques such as lithograph and wood engraving, (2) crop of great illustrators and caricaturists like Grandville, Daumier, Travies, and Deveria, (3) freedom of press accorded but soon oppressed by the King Louis-Philippe, which created the "golden age of caricature".Though it is crucial to know the artistic traits of this period, we have not yet attained the level of sufficient appreciation of the full extent of the characteristics of lithographic prints and book illustrations produced then. In this study, we have tried to find a clue to that knowledge.First we collected as many plates and illustrated books of this period as possible. Then we picked out their important elements -- mythological, literary, political and historical themes that recurrently appear in these works --, and classified them. After that we analyzed the works, referring to contemporary text-documents.The following are some of the new findings obtained in our study.1 . There are some variations in the frontispieces of "la Caricature" and "le Charivari". By comparing them, we have clarified what political characteristics the editors tried to give to these satirical newspapers.2. We compared different versions of some hand-colored plates issued in "la Caricature" and have elucidated the editor's strategy for evading the censorship of the government.3. By historical tracing of the relationship between the illustrator Daumier and the critic Baudelaire, we have situated their shared aesthetic values in the artistic and literary context of the time.4. By examining the relationship between Daumier and the art critics of his day, and by studying his caricatural plates satirizing the contemporary arts, we have made clear the peculiar position of this artist
