We don't do pill IDs here and we don't do reviews of sources or discussion of sources.
It is very common for Valium (diazepam) to have different imprints (what you are referring to when you say "logos"). Diazepam is an extremely common drug worldwide and there are probably hundreds of different imprints for diazepam worldwide. Again, that's not what we do here. There are whole other sites and other forums devoted to pill IDs. Do a Google search.
