I have read some discussions of this photograph that reference the irony of its creation. Supposedly Strand used a modified Graflex SLR at this time with a fake lens pasted at right angles to the real lens. This allowed him to photograph subjects who believed he was photographing something else. The irony here is that it appears the blind woman is glancing to the right. We have no real way of knowing if this is true. But if this is indeed the case, there is something nicely ironic about a photographer pretending not to see the person pretending not to see. No way now to track down the two actors in this, and all we are left with is the picture. Which is still pretty cool.
