Question: In multiple episodes we see a box hanging just inside the barracks door. What is that? It is mostly blue, and appears to have flowers or something painted on it.
Answer: After careful inspection, the aforementioned box is a decorated holder for the boxes of long matches needed to light the stove.
Chosen answer: In different episodes of "Hogan's Heroes, " the arrangement of items in the barracks varies. Sometimes there is a sink on one side of the door. Sometimes there is a chest of drawers on the other. I have seen episodes where a hanging box is there, as you describe. To my eye, the decoration appears to be a kind of camouflage design. I had assumed it was where mail was delivered to the prisoners. It could also be a storage for small items, such as a medicine container. I don't recall ever seeing it opened or otherwise used. Normally, in situations like this, when questions arise regarding set pieces, set decoration or costumes, I attempt to look up the show's crew members IMDb.com to pose the question to the source (when I can find them on, say, Facebook). In this case, however, all of the gentlemen responsible for set decoration on "Hogan's Heroes" have since passed away.
I have the series on DVD, and have been able to scrutinize the blue box. It is a decorated holder for the long matches used to light the stove. Occasionally, you can see part of the word 'matches' through the slot on the side.
Chosen answer: It was neither of those. In earlier TV shows, it was typical that each episode was a self-contained story, and the plots and non-regular characters were rarely carried over from previous shows to the next. Any problems or situations were resolved at the end, even if some plot threads were illogically left unexplained. This allowed episodes to be aired in any random order. Today's TV series usually have ongoing linear timelines and continuous plots that are played out over multiple seasons.
