The 8712 Technic Figures from 1988
were a way to expand your collection of Technic figures which would be
otherwise difficult given their relative rarity at the time. This
set came with 3 figures. The two with Technic logos on their chest
are unique to this set, but the one with suspenders appears in the
Rally sets in 1990. The monkey wrench never appeared in another Technic set.
This was one of three times that Technic figures would be released as a supplementary set.
