Both notes, with a denomination of 20 yuan, feature the official emblem of the 24th Winter Olympics on the obverse.

两款纸币面值均为二十元，正面均印有第 24 届冬奥会会徽。

What Dr Gupta has shown, though in software rather than in the real, biological world, is that the obverse can also be true-changes in body morphology can optimise the way minds (or, at least, derls) work.
