The engraving of dedications on silver cigarette boxes is a common practice.

Browsing within my small collection of "tobacciana" I've found some examples of dedications.

this silver cigarette case was made in Germany around 1935. The interior is gilded and engraved with the inscription   In remembrance of all the lovely valses we danced together

It is hallmarked ' half-moon and crown ' and '900 ' (purity 900/1000 used in Germany for higher degree silver). The cigarette case is square shaped with cabochon thumbpiece and gold monogram.
