Which Pre-1949 China Stamp Is Considered Most Beautiful?

In many countries, one stamp would be commonly accepted as the most beautiful stamp of that country in terms of its design and artwork.

Some examples include
- UK: 1929 PUC One Pound (Scott 209)
- US: 1898 Trans-Mississippi One Dollar (Scott 292)
- Canada: 1929 'Bluenose' 50c (Scott 158)

Just wondering if there is such a commonly accepted stamp for pre-1949 China.

If there isn't, which one would YOU vote for?

You may find some pushback on the 'commonly-recognized' choices above (though probably not from me...).

For China, it is hard to beat the 1909 Temple of Heaven set of three bicolors. Here is the 7c high-value issue of the set, Sc#133:



If bicolors aren't your thing, then perhaps the 1923 Temple of Heaven.

The first airmails, Jenny over Great Wall, are classics, too.

Now, let's see if any of these are 'commonly-recognized' by our fellow SCF'ers.

I like this one among the many beautiful classic Chinese stamps:

I knew someone would say this



I like these ones:

If we're including the Treaty Ports (and no reason why we can't) then the Chefoo bicolors are a favorite, too.
