Even though in England, Mary Tudor outranked her husband Philip of Spain (she was Queen Regnant, while he was King Consort), she was still shown as a traditional subservient wife in their joint seal.
On the obverse, Philip is in the dominant position seated on the left. On the reverse, even though Mary appears 'first' on the left, it is her husband who is more prominently depicted. Mary looks squeezed in.
