I did not see reference to this story anywhere on the Casebook so thought I'd post it here. It seems some items belonging to Insp. Helson of J Division (a lead investigator in the Nichols murder) were recently put up for auction:

Just a moment...
https://www.antiquestradegazette.com/news/2024/jack-the-ripper-items-from-police-investigator-come-to-auction-for-the-first-time/


Included are some photos and info on suspect Ostrog, Helson's copies of the Dear Boss and Saucy Jacky communications, a photo of Helson (has this been seen before?), as well as this very interesting item:

"Among the items to be sold are a mortuary photo of Nichols which, although faded, seems to differ from the known photo with the camera at a very slightly different angle."

The mortuary photo is difficult to clearly see in the site's photos.

Would love to hear some thoughts on all this.

The file contains copies of the taunting letter and postcard the notorious, but never identified, serial killer sent to police.



​EDIT: Sorry --- Just saw reference to this was made under Ostrog.
