Romantic postcards

My Grandfather emigrated from Bulgaria to the States in about 1920, leaving his sweetheart behind with the intention of soon returning to marry her and bring her to a new home in the USA. It took him 5 years but return he did. I like to imagine that these postcards with the romantic themes were ones that he and Grandma wrote to each other during those 5 years of separation. They are all written in Bulgarian so I have no way of knowing.

Who are those Viking looking fellows lurking in the background of the above picture? What is this liaison all about?

I find these to be such lovely cards and I hope you enjoy them too.
Be well.
