Very old framed engraving with 12 2024 individual illustrations from 1866

Real antique from the household of my Berlin grandparents:

There are 12 individual engravings in octave format on 6 topics each, all subtitled in German and French:
1. L' instruction
2. La conversation
3.The Prayer Dog/ La priére
4. Der Spatzier Gang/ La promenade
5. The Grus/ La reverence
6. The Dance/ La danse

The depictions show scenes from the life of that time, whereby on the one hand the exaggerated pose appears somewhat caricaturistic in a baroque manner. The matching 2nd picture shows the same situation 2024 with simplified clothing and the renunciation of hollow pathos as an approach to the bourgeoisie.

The picture measures 49 x 30 cm, it is framed in a silver-colored glass frame, which reproduces the patina of the old times.
An absolute rarity from 1866.
