Bonjour,
This is a poster who announce the sale of mans and females slaves, wich will take place Monday 18th of may 1829, under the three.
On this poster, we can see the names of the slaves and their identity (the name, the age and the profession).
Down the poster, we also see the sale of books, grain, paddy ect, at eleven o'clock, the same day.
And lower, we can see that an assembly will take place at one o'clock, who will celebrate an english horse named Blucher.
