Several early scholars point to this Dobbins "sketch,"
dated 1804, that is at present in a private collection as the source material for Rogers' version of the Boston State House views. The only
version available for study is a later reproduction created for a 1910
book by Mary Ayers, titled Early Days on Boston Common, seen here. Versions of this image are in the collection of the Bostonian Society, along with a pair of hand-colored children's drawings, one of which appears on the back of a piece of 18th
century Italian sheet music. There are clear problems with the Dobbins' sketch as the source for Rogers' view. The cows are different, as the one
standing cow is grazing with its head down. In addition to the grouped cows in the
foreground, the boy and wheelbarrow in the middleground, Dobbins' painting also contains a woman,
child, and babe-in-arms in the extreme left foreground. This grouping
does not appear in any other version of the image. Additionally, the
Dobbins' watercolor has a different, and more distant, perspective on
the Common and State House.
