In part: “I wrote you a v mail letter today and told you I had a letter from St. George…. I also had a three installment V mail letter from Aunt Mattie and I was so glad to get it. It was interesting and contained a lot of news of you and the two little boys…. It was sweet of her to write me as she did…. I did not get any mail from you yesterday or today. I miss letters from you when they do not come. I hope some will come tomorrow. I adore you.” Intersecting mailing folds and mild handling wear (a few tiny marginal stains), otherwise fine condition.
