Perhaps this is cheating, but before the introduction of the true minifig in 1978 (the armless-legless version came out in 1975), the scales of LEGO sets were all over the place. Many of these sets were at a smaller scale than the now-ubiquitous fig-scale, so by the definition I've been using in this blog, these are fair game. Particularly in this case, which was either my first or second set ever (either before or after Universal Building Set 111): 435/612 - Tipper Truck.
Tipper Truck was released in Europe in 1974 under the number 632 and in the US the following year under the number 435. It is made up of only 17 elements, including that odd blue tipper bucket piece (that I still have!).
