1930s Valentines, Cards, and Letters

My mom was born in 1927 and was raised in a Mormon family in a small farming town in Northern Utah. My grandfather was heavily involved in the Mormon church (I think he was a Bishop over a Ward). This Fast Offering and Ward Maintenance Record book was given to my mom and her siblings. A collection of valentines, cards, and letters were carefully attached to the pages in the book so that the backs of each Valentine could be seen, every letter could be taken out of its envelope, and every card could be opened.
