** The 1958-73 episodes that survive and circulate include October 15, 1958; February 9, 1959 (hosted by Art James); September 12, 13 and 16, 1963; a 12-minute clip from 1966 (which may be from a video on [=YouTube=]--it starts with the resumption of a game from March 29, 1966 then has the game's start from the day before spliced in after); a September 1967 episode; October 2 and 3, 1967; December 24, 1968; a September 1969 episode; December 24, 1969; a ten-minute clip of a color videotape broadcast from July 23, 1971; March 23, 1973 (the finale, and the only full episode known to survive in color [[note]]The solution of the first puzzle is missing [[/note]]π). A few shows from spring 1971 are at the UCLA Film & Television Archive, paired up with that day's ''Series/SaleOfTheCentury'', and a few others are held at the Library of Congress. Of the rest, a lot is likely to be lost forever due to the poor preservation practices of the era. [[note]]An unsourced claim on the show's Wikipedia page says that this version is now owned by [[Creator/{{CBS}} CBS Television Distribution]] due to fin-syn rules, which may or may not explain NBC's reluctance towards allowing reruns.[[/note]]

* [[LastOfHisKind Last Of Its Kind]]: Long after most of NBC's programming, even the daytime game shows, had switched to color, producer Norman Blumenthal had resisted switching ''Concentration'' from black and white. One story had it that he believed coloring the pictures in the rebus would make the game too easy and refused to allow the show to make the switch. Finally, at the end of October 1966, a deal was worked out to keep the rebuses monochrome but the set would be remodeled and the show finally make the switch from black and white to color. In doing so, ''Concentration'' became the last NBC series to switch from black and white to color.

** The abundance of neon lights and palm trees on the set and the presence of a younger, mustachioed Alex Trebek unquestionably date ''Classic Concentration'' to the late 1980s.
** This trope is even stronger for a viewer that's a car enthusiast, because ''Classic Concentration'' had a tendency to give away obscure cars that had short production runs, such as the [[https://en.wikipedia.org/wiki/Merkur_XR4Ti Merkur XR4Ti]], [[https://en.wikipedia.org/wiki/Eagle_Premier Eagle Premier]] and the [[https://en.wikipedia.org/wiki/Subaru_Justy Subaru Justy]]. Similarly, ''Classic Concentration'' was seemingly always giving away a Hyundai Excel, a car [[TheAllegedCar that's now-infamous for his poor quality]], which lead to it being withdrawn from the American market after only a few years as Hyundai wanted to [[OldShame push it into obscurity so they could rehabilitate their reputation]]. This trope goes UpToEleven for the [[https://en.wikipedia.org/wiki/Daihatsu_Charade Daihatsu Charade]] they offered as a prize car reoccuringly in 1988, as Daihatsu only sold cars in the United States for four years before hastily leaving in 1992 and most Americans today have no memory of them.
