I was browsing through antique photos on Flickr and came across
this.
This might be old news for some, but it's new to me. And blows me away a bit. I was pleasantly surprised to find this.
Any lover of historic or photojournalistic images should love this gallery / photostream. Right now, there are over 3,700 quality, high resolution scans from the original negatives, positives, plates, and prints in the gallery. More are consistently added about once a week.
