Incredibly rare collection of 21 signatures from the crewmembers of the MIR-21, MIR-22, STS-79, STS-81, and MIR-23 space missions, all signed aboard the MIR Space Station on a flown envelope which spent over six months in orbit. The signatures include: ONUFRIENKO, USATSCHOW, LUCID, KORSUN, KALERI, ANDRE-DESHAYS, READDY, WILCUTT, APT, AKERS, WALZ, BLAHA, BAKER, JETT, GRUNSFELD, IVINS, WISOFF, LINENGER, ZIBLIJEW, LASUTKIN, and EWALD. The envelope was postmarked five times on the face, and the reverse bears a handstamp signed by MIR-22 cosmonaut ALEXANDER KALERI, whom therein attests to the envelope's authenticity. Fine condition. Sold with an additional letter of provenance from the Astro-Philatelie Service.
