Here’s an Easter card that I guess should go with the “unnumbered cross greeting cards” set, although the Artistic Series trademark is different from the other two similar cards (one of which is “Prize Exhibition Series”, while the other is “London Registered”). The size is the same, 3.125" x 4.375".
@justintanner The new card simply has an “Artistic Series” trademark, not “Prize Exhibition Series” as you put in the Item Comment. That trademark appears on the “HOLY AND HAPPY CHRISTMAS” card, while the “HE DIED FOR US” card has a “London Registered” trademark.
Ooops I’ve changed the artistic series, thanks again.
