The OTS is a component of the CIA which provides it's "gadgets" to do it's spying - see description below.  This very poster was highlighted in a book which describes the OTS titled, "Spycraft : The Secret History of the CIA's Spytechs from Communism to Al Qaeda", authored by Robert Wallace and Keith Melton in 2009.  The last two photos show the title page of that book and this very poster with the caption, "OTS 50th Anniversary Poster, 2001".  

I have two versions of this poster online for sale - one larger and this smaller version.  This one measures 11" by 8.5" and is in EXCELLENT CONDITION.  It is made of thick paper - cardstock.  There is light corner wear, lighter edge wear, and a slight curl on the bottom from storage (see listing photo).  The are no scratches, pinholes, or marks - it is unused.  No markings on white back of poster.  The larger poster size is 17" by 11" and can be found at eBay listing # 296189968290.  Just put this number into the eBay search bar.

On the OTS from Wikipedia:

"The Office of Technical Service (OTS; formerly known as the Technical Services Division and Technical Services Staff) is a component of the U.S. Central Intelligence Agency,[1] responsible for supporting CIA's clandestine operations with gadgets, disguises, forgeries, secret writings, and weapons. The OTS traces its history to October 1942, when OSS director William J. Donovan created the OSS Research and Development Branch, a technical group tasked with creating "dirty tricks and deadly weapons" to combat the US's World War II enemies.[2] Donovan named Cornell University-trained chemist and executive Stanley Platt Lovell as the branch's first head, a man whom the CIA remembers as the "founding father" of the OTS.[3] In the 1950s and early 1960s it also researched, investigated, and experimented with the use of drugs, chemicals, hypnosis, and isolation to extract information during interrogation, as well as to make it easier for American captives to resist interrogation. OTS is part of CIA's Directorate of Science and Technology."
