With thanks to Chris and to Tomizawa-san, for suppling and educating, we weren’t able to translate the extensive old-fashioned pencilled notations on the reverse of this unmailed card.  We think it dates from 1929.  If you are an expert on classical Japanese, let us know and we will send a scan of the reverse to you.  The card is separating from itself, but not yet split.  Grade: 4
