Neil Armstrong's personally-owned rare Apollo 11 crew patch manufactured by Texas Art Embroidery, measuring 4˝ in diameter, featuring a very accurate embroidered rendition of the mission insignia. This patch design was worn by the crew on their Biological Isolation Garments at recovery time and then later on their blue post-flight jump suits. The Texas Art Embroidery Apollo 11 'Bio-Garment' patch was released in very limited quantity and only made available to the crew and NASA employees. Mounted and framed to an overall size of 6.75 x 7.75. In very fine condition. Accompanied by a typed letter of provenance from Armstrong, addressed to John Osterweil, in part: "Enclosed is an Apollo 11 Space Suit Patch. It was not on my suit, but it is one of the same original batch used on the flight." Also includes the text of a 2012 article published by Osterweil in Tampa Bay Online, documenting his friendship with Armstrong and referring to the gift of this patch.
