Here is a photo of the “Big Three” with Art. Not sure whether that makes the “Big Four.” ;–) This is the only group photo I’ve come across so far of the first four Wright children without the fifth. There may be others in the archives that I haven’t come across yet (photos, not children ;–).

It’s a cold morning sometime in the winter of 1941-1942. It could be before or after Dorothy was born in January.
It is remarkable to me how much all four look like miniatures of their adult selves (well, except for Art’s facial hair) at these young ages. Sometimes with photos of children it isn’t easy to identify them based on how they look as adults. But there isn’t any mistaking these four (to me, anyway).
