10" x 18" or 25cm x 45cm.

The white enamel is in relief - excellent definition.

This sign was made in 1970s and is from Lille.

Jean-Baptiste Colbert was Prime Minister and held several financial offices before his death in 1683.

Slavery was important to the French economy.  Colbert initiated the legal disenfranchisement of all persons of colour in French colonies and the legal definition and conditions of slavery.  It became the Code Noir.  It also ordered that all be converted to Catholicism and that all Jews be expelled.

A statue of Colbert outside the French Parliament was vandalised in June 2020 for that very reason.

As in UK, there is current heated debate about locations named after the slave trade and, in particular, its perpetrators.  The prevailing argument appears to be that it is better not to erase history by removing or renaming but to recognise what happened and supplement the statues and street signs with notices.  Whichever, here is one such sign.
