Sometimes we get lucky and find one of those antique lamps that used to hang in the old general store or at grandma's house.  This one has the retractor in the crown.  This enabled you to pull it down to trim the wick, add oil and light it.  Then give it a gentle push and it went back up to the ceiling.  The roses are on the inside as this is the view most people had of the lamp.  With the high  10 -12 - 14 foot ceilings most folks built before the turn of the century (this allowed heat to rise above the family or customers) few if any would see the outside of the shade.  When lit the art work does show through to the outside.   Both of these lamps still burn lamp oil as originally configured.
