French Architectural Prints

I came across these antique French prints at an estate sale a few days ago.  I couldn't afford them, but the pics were free!

 The first print shows a fireplace elevation, the ceiling above and a section to the right and the tile floor plan on the bottom.  If my French translations are correct, it is for a dining room.  Isnt the wallpaper pattern on the walls and ceiling great ?

 The second print is for a painted design on a ceiling.  The top section shows the profile section thru the plaster moulding.

The last print shows the wall paper pattern for a parlor or living room at a hotel.  The bottom drawing shows a plan view section of the wall and how the doors sit it in.  The strikingly handsome reflection in the glass is yours truly ;)
