Surviving piece — western Atlantic focus; Ottoman compilation from multiple source charts.

Mainstream — eastern South America; southern bulge = further SA coast / distortion.
Hapgood / Ohlmeyer lineage — southern sector ≈ Queen Maud Land / Palmer under ice; “mapped before ice.”
Sietch use — exhibit of contested coast geometry; pin on Map Room “map-anomaly zone.”
