This card was sent to Master W. Trautman, 211 E. 104th St., New York City:
You please me very much by your attendance and study. Keep up the good work. Have a chapter of Psalms for next Sunday. Kindest regards. L.M. Kliefoth
Master being the proper address for a young man at that time! The postmark is a bit fuzzy because some of the print rubbed off, so I'm guessing it's circa 1911.
Happy Postcard Friendship Friday, and kindest regards to our masterful moderator, Beth at The Best Hearts Are Crunchy.
