"He, She" what could they be?

I am a little curious as to what I have here. 

 I found these "He, She" cups at a thrift shop in
Massachusetts while on vacation a few weeks ago.  

The rooster had me thinking egg cups or custard cups,

 but now I am leaning towards my husbands guess of tea cups. 

 I'm not finding anything similar on etsy or ebay to give me any clues, 

so the mystery may never be solved.

Any ideas?
