The ranks that are written on the poster board by the artist are Army ranks. I have changed these to Naval ranks and translated these to English. I have also added these with Pictures 3 and 4. To my knowledge Napoleon's Marines had Naval ranks.
1. Infantry de Marine: Drawing 1. Captain, Grande Armee. Picture 2. Battalion Commanding Officer, Colonial Navy.
2. Infantry de Marine (First Picture Only): Picture 1. Ensign Second Class. Picture 2. This drawing is of the uniform of a junior Army Officer of the Infantry of the Line and the Light Infantry.
3. Infantry de Marine: Master, Sapper, Grande Armee.
4. Infantry de Marine: Seaman, Company of a Hundered, Grande Armeee.
