In this unused and very old postcard we have two “…est” examples in the reverse caption:  “one of the largest structures for religious worship in the World,” and “one of the finest pipe organs in existence”.  Not being certain of the current status, we’ll just advise you to notice the significant remnant of tape along the card’s left edge.   Note too that these older cards didn’t worry about putting “Mormon” in quotation marks.  Grade: 3
