This place card was made by Hallmark in the 1930s. The manufacturing mark used at that time was a simple “H” within a circle. (You can see it toward the right end of the card.) Hallmark’s designs then were, for the most part, rather pedestrian. Today’s market doesn’t value Hallmark’s vintage output in the same manner as it does the vintage output from Beistle, Dennison or Gibson.
