Do you have the photos from Studio 35?
Answer
At this time we are unable to confirm if we have the negatives from Studio 35 in our Aaron Siskind archive. Unfortunately these negatives are inaccessible due to current construction to our cold storage facility. I have tagged this question, and we can reach back out to you when Siskind's negatives will be available. Once the negatives are accessible again, we will be able to search more for the photos you are interested in.
We have confirmed with the Aaron Siskind Foundation that the vertical mirrored diptych is credited to Max Yavno. However, we are unable to locate this photo in Yavno's archive. We do own the copyright for Max Yavno and if you are interested in permissions then please visit our Services for Publishers page for more information. While we do not have this photo, through our correspondence with other institutions, the Ad Reinhardt Foundation appears to have the negative of this image in their archive. I would suggest contacting them to see if making a high resolution image is possible.
