Looking at the photograph from Brooklyn Historical Society, we observe:

African-American family in the foreground

• wearing casual clothing
• helps us date the photograph
• child petting cat
• broken railing
• graffiti
• screens
• curtains

Orthodox Jewish family in the background:

• formal attire
• air conditioning
• blinds in the windows
• fallout shelter (do all buildings have this?)

Overlaps:

• racial/ethnic/religious overlaps
• socioeconomic overlap
• new vs old home technologies/outfittings
• recreation vs. not
• ornamentation vs. worn-down buildings

Thesis statement:

• Despite their location next to each other on the block,
• Although both houses have similar architecture,
• The two families differ in their appearance and activity, yet they both

Organization:

• block format
  • all about one
  • all about the other
  • comparison
  • or
  • all about one
  • all about the other with comparison to the first
• point-by-point
  • one element and comparison
  • another element and comparison
  • another element and comparison etc
• a combination of the two

Including quotations

• introduce it
• quote it (and cite it)
• interpret it: “In other words…”
• analyze it
• apply it back to your thesis
