Concordance
Thematic: Excellent. There is total harmony between the stamp, the postmark, and the postcard illustration, all dedicated to the central figure of John Calvin and the institution he founded in Geneva.
Geographic: Perfect. The postmark is from Geneva, the city where Calvin developed most of his theological work and where the celebrated university was established, giving historical and geographical value to the set.
Temporal: Very strong. The June 1959 postmark is situated exactly within the period of the 400th anniversary celebrations of the university (1559-1959) depicted on the stamp, respecting the principles of maximaphily.
