It makes me curious about this specific example if the painter copied another painting of the king or he managed to somehow get time with the king in order to know what he looks like for the commission.
That is unlikely for all kind of reasons. Chiefly among them that when the painting was painted the King was long dead.
The painting is dated to around 1590 while Henry VIII died in 1547.
In exchange there are flags and political posters and signs on lawns, and religious representations in some religious households.
I recently read a longform interview of someone who married into the Pelosi family. Apparently, at least at those levels, a "vanity wall" with pictures of yourself/your family with famous folk (in this case: former presidents, perhaps foreign statesmen) is common.
I tried googling for that phrase... it matches a piece of bathroom furniture, instead of a wall of photos showing off you know famous folk in your expertise.
