That huge case of "Gibbons Dog Burgers" were actually "Gaines Burgers." From 1961 into the 1990's, "Gaines Burgers" were cellophane, individually wrapped hamburger-like patties. They were sold to dog-lovers for dogs to love.
After returning from Salem, viewers seen a totally NEW Stephen House. The last of the "Columbia Ranch" Fires leveled the Bewitched Set. This episode shown a NEW stairs, wallpaper Foyer and Den/Kitchen hallway. Stairs and a normal counter and sink. The living room was still a mystery. A shot over Endora's shoulder seems to show a window where the pair set of French doors once stood. The Den was the part of The Stephen House that change dramatically.
People talk about the dramatic change in the kitchen when discussing after the Fires and return from Salem, MA. Yet, it was The Den that changed. Fact is that there where camera shots viewers never had seen before. First, the gable-like windows on the front of the house made it on camera - from inside Den. This is where the dog hides under the drafting table. Facing the windows from the main Den Door, the Fire place was on the right side, closet door and wall was on the left. Viewers seen the fireplace on the left side on the other side of the Foyer wall embedded in dirty brick. The left side was one wall, but viewers seen the wall with a closet wall and door. Den wall entrance was done in Pine Wood. The other wall (that once had the fireplace) never made the taping.
It took 6-years and a studio fire for viewers to see inside The Den Closet. Once it was on a straight but diagonal wall with the hallway wall not having a door and having a door to not having one. But, the Den Closet became a square wall with the former diagonal wall. That wall extension gained a fireplace, too.
