Correction: In both this post and a previous one, I referenced the Simpson letter. However while RR Auction lists this as part of the December auction, the letter was bought earlier this year by Titanic Foundation and brought to Belfast for exhibition. In fact, it was exhibited during the summer. In short, I got it wrong. I kick myself for not checking my own news archive about this.
At the recent RR Auction the top bid for Titanic iceberg photo was $21,000. Not all items were sold and a third auction is being considered next April. So far, there is no report that the Simpson letter was sold.
