Oakley was most likely aware of his older brother's rendition, since they often worked together before Howard died in 1878. However, Oakley chose a completely different vantage point for his drawing and made some significant changes.
In his drawing, Oakley re-oriented his presentation, viewing the town from the southeast. In this drawing, correcting his brother's error, he drew the train station as it had actually been built. He also relegated it to the lower right corner, neither displaying it prominently nor labeling it.
His brother had included a legend identifying twenty-four important structures, primarily factories and commercial buildings but no public buildings. Providing a more balanced coverage, Oakley expanded his legend to identify thirty structures. His list includes city hall, the court house, a school, seven churches, three hotels, and seventeen factories.
Both drawings prominently display the two large textile complexes. Oakley reverses their relative position, however, placing Nashua Manufacturing Company on the left and the Indian Head Mills on the right.
