The profile of The Queen, that Guignot has posted out of Hong Kong, seems to closely resemble the standard profile for QEII when she is not the dominant figure in a GB stamp, such as was introduced in SG689:
it seems very close to the HK stamp, perhaps only being machinized, as in looking like a bas relief:
This profile is still, to the best of my knowledge, still being used as can be seen in the recent example from 2009:
This profile is by my count, the third (I could easily be wrong since I don't know don't bout nothing) of the profiles used for QEII, the first two being the Wildings and Machin profiles. Alas, I don't know who did this profile but it is very nice and has been, I'm sure, adjusted over the years.
