Tin Postcard with Black Dachshund in forefront & a Handwritten French Message

This is a decorative sign featuring a dachshund silhouette on a background that resembles a vintage French postcard. The sign is made of a heavy-weight metal and is designed for wall hanging. The text "CARTE POSTALE" is French for "postcard". The French stamp in the top right corner features the number "12" and the text "RÉPUBLIQUE FRANÇAISE POSTES". The handwritten script includes a name, "Monsieur André," and the city "Paris". It is 14 wide x 10.5 tall and comes with wire hanger. The back looks like brass but I don’t know what it’s made of. EC.
