These three photos were apparently taken on the porch of the house the Lloyd Wrights lived in, in Monroe. Since the clothing seems to match what is in the Easter group photos of that year (in this previous post), evidently these photos were taken on that same day.
Each of these would be a really good photo of its subject but for the abundance of graininess, dirt, focus issues, and fading over time (unfortunately).



There surely must have been similar photos taken of Kathryn and Dorothy on this occasion, but they are not with the above photos in the album I am working through. Possibly they will turn up elsewhere.
Arthur, you were SO cute! Still are, actually!
Regarding Clara, her clothing is not doing her any favors. Oh well: all that soon changed!
