Lovely drawing of a blooming rose with three buds. The Book of Roses was written and illustrated by Francis Parkman (1823-1893). It was published in 1871.
This is the second rose drawing that I’m sharing from this book. You can see the first one here. This blooming rose with buds drawing would look lovely just the way it is or colorized to match your project.
