Mr. Charles E. Hulse, an automotive historian who specializes in early Oldsmobiles, has written to call our attention to an error in a picture caption for the article about William C. Durant that appeared in our August, 1973, issue. Mr. Hulse writes: I would disagree with the identification of the photo in the upper right-hand corner on page thirteen. This auto is not an Oldsmobile but a R.E.O. , of 1905 or 1906 period. The man seated behind the wheel is not R. E. Olds. In fact, I fail to find Mr. Olds in the photo. I would identify the man behind the wheel as Mr. H. T. Thomas, a R.E.o. official.
