"What glasses is X wearing in the movie Y?"
If you are trying to identify a prop used in a movie/show, it could be on topic for Movies.SE. Make sure you read their meta or ask if you can't find anything.
- "Does anyone know which table was featured in X?"
- "Who makes this poster?"
The other two, are for most not fitting for the Stack Exchange Q&A style by the kind of quality they tend to attract. If you have a question about something like this, make sure you actually can't find any information (and by that I mean reaching the second page of Google results), and even so isn't sure that your question will be well retrieved.
