Organizations not related to ASTP

I had no intention to collect covers from unrelated organizations, but they just appeared in my collection. So I present them in a separate section. Observatories, museums, institutions, etc.

I will also include here the covers commemorating the events that are part of US-USSR cooperation in space but not directly related to ASTP.
