ID Help: Pair of Mid-Century Oil Portraits found in Kortrijk, Belgium. Unusual signature placement.

The Details:

​Location Found: Purchased in Kortrijk, Belgium (West Flanders).

​Medium: Oil on Canvas.

​Signatures: Both are signed. Interestingly, the man’s signature is bottom-right, while the woman’s is top-right.

​Markings: A specific serial number is written in pencil on the back (no date visible).

​Era: Judging by the hairstyles and fashion (pearls, bouffant hair, wide-collar tie), they appear to be from the late 1950s or early 1960s.

​Description:

I’m looking for any information on the artist or the couple. The man bears a strong resemblance to European royalty (initially thought of a young Prince Charles, though the timeline may not match).

​They are high-quality oils, likely a commission for a prominent local family. Since they were found in Kortrijk, I suspect they could be part of the Flemish "society portrait" tradition of that era.

​Questions:

​Signature: Does anyone recognize the artist? The "top-right / bottom-right" placement might be a stylistic "trademark."

​The Serial Number: Does this pencil format suggest a specific Belgian gallery or auction house?

​The Subjects: Do these faces look like known public figures or members of the Belgian/European nobility?
