Edit
A sign found mostly around taverns, coffee Shops, Stores, Boulangeries and so on.
Can be found placed on the floor, on the wall or hanging from a horizontal pole a few meters above the ground ( although it is quite rare ).
Chalkboard signs are characterised by their Dark Green or Black surface, placed on a wood or ( rarely ) polymer frame.
Chalkboard Signs are not Chalkboards !
Chalkboads signs are used the same way a small catalogue is used. They're meant to display offers, discounts or simply Products/Dishes/Beverages sold in the store.
Defining features : Frame - wood , polymer ( rarely )

Placement - Floor/Ground , Wall , Horizontal Pole ( rarely, always above ground )
