A "Winter Sky," a solitary fir tree on a snow-covered hill with the sun struggling through a cloudy veil and glistening on the ice-crusted branches. Stieglitz has tried himself as a virtuoso. The effect is remarkable… (Murray)
A landmark in photogravure and photography as fine art.
It was during Stiegitz’s years as editor of Camera Notes that he began exploring the artistic possibilities of photogravure. In 1897, the very year that Camera Notes commenced, the prestigious publisher R. H. Russell issued Picturesque Bits of New York and Other Stories, a portfolio of twelve of Stieglitz’s best-known early images printed as oversized photogravures. So important was this project to Stieglitz, that he personally made the transparencies used in plate making, and then supervised the printing of the entire edition of photogravures. So pleased was he with the results that he signed a limited deluxe edition of the portfolio and allowed the photogravures to be sold individually. Stieglitz felt these prints had high-art value and were no less intrinsically works of art because they were printed by photogravure. Such photogravures joined the great tradition of fine printmaking established by artists like Durer and Rembrandt. 
We have been accustomed to see the fine tones and graduations of our best workers so utterly ruined in the process of engraving and printing that we are agreeably surprised at the wonderful delicacy and transparency of these examples. They are printed on heavy plate paper, 14×17 inches, and each plate is presented in a color appropriate to the subject. We might take exception to the tint employed in the “Glow of Night,” where the desire to reproduce the yellow glare of the incandescent and other lights glowing through the fog and mist of a rainy night on Fifth Avenue has led to the employment of colors that are singularly disagreeable. Perhaps our photographic experience heightens this repugnance, because the tones, ranging from yellow to a somewhat dirty greenish black, recall the effect of an aristotype badly sulphurized in a combined toning and fixing bath. It is possible that the print will be more satisfactory to an artist, or to an art lover, who has never dabbled in photography. In all the other cases the colors are admirably chosen. 
The photogravures were printed in an edition of twenty-five on plate paper using different ink colors. Stieglitz himself made the steel engravings from the diapositives (positives made from negatives) and used rapid plates to preserve the detail and softness of the originals. In addition, he directly supervised the printing of each image. Picturesque New York was apparently an earlier title of the portfolio. 
The pictures vibrate with atmosphere–fog, snow, streetlights reflected on wet pavements. The word “bits” suggests fleeting impressions caught by a highly selective eye, the crystallization of experience similar to the effects sought by Ezra Pound and Hilda Doolittle in the Imagistic poetry they would invent in the next decade. 
A two-page advertisement for the portfolio appeared in a small catalogue issued by publisher RH Russell in 1897 stating specifics for the portfolio as well as photographs, which Stieglitz sold individually. The twelve subjects, together with an introduction by W.E. Woodbury, are issued in an artistic portfolio. Price, $10.00 There will also be an Edition-De-Luxe in a special binding, limited to forty copies of the first impressions, each plate signed by Mr. Stieglitz. Price, $25.00 Single Proofs of any of the plates. Price, $2.00, each. Artist’s Proofs, signed by Mr. Stieglitz. Price, $5.00, each.
Even with this marketing push by RH Russell as well as others, it is doubtful that many of the Picturesque Bits portfolios were sold, especially the $25.00 Edition-De-Luxe edition signed by Stieglitz. Book seller catalogues around the turn of the 20th century remaindered original $10.00 “ordinary” copies of the portfolio to $5.00. The now accepted total copies of this seminal portfolio in the history of photography numbers a mere 25 copies: “The photogravures were printed in an edition of twenty-five on plate paper using different ink colors.”
