On these two un-numbered examples the signature, instead of being incised as usual, is impressed, ie 
pressed in with a stamp. The depression made by the stamp can be seen surrounding the word Pamela. 
Impressed signatures are extremely rare. 
- Another recorded example is an impressed PPP monogram on an un-numbered ashtray.  
- An impressed signature on an un-numbered Pamela 8 basket has been gone over with the incising tool and  '1934' added. 
With so few examples it is not possible to draw a firm conclusion but it would seem that this method of marking was briefly trialled in 1934 but soon abandoned.
