Here's a close-up of the picture.
And here's the back of the card, sent to Mrs. Ella Bass.
The message reads:
Good Morning. just arose from my bed of slumber. katy B. slept with me. Chas R. and Ray B. stayed all night. will go home today. The autatorium will have a cement floor. it will be a large building. the carpenters will begin next week. As Ever (illegible signature)
The card is postmarked Syracuse, but I'm pretty sure that was Syracuse, Indiana not Syracuse, New York. Syracuse is located near Oakwood Park, a religious camp and meeting ground, which is where the auditorium was being built. The original 1898 tabernacle burned down in May 1914 and was then rebuilt in August 1914.
