Heraldic vintage postcards

I've recently come across several vintage postcards that display a coat of arms or a crest, specific to a location or university. Some of these are printed on the card, whereas others are embossed.

A curious addition to the postcard, probably dating back to when people felt a stronger need to belong to or be part of a certain place, and definitely back to a time when people showed more respect and allegiance to the royal family than perhaps today.
