This is the record for the sheet you bought: which original it comes from, how it was digitised, what we did to the file, and what we are allowed to sell. Nothing here is marketing. It is the paperwork.

Which painting, and why this one
Rousseau never left France. The jungles came from the Jardin des Plantes, the Paris hothouses, illustrated magazines and a taxidermy collection, assembled leaf by leaf into places that do not exist. This is one of the late ones, painted the year before he died, and the last of the great jungle pictures to leave his studio.
The provenance reads like a history of the early modern trade: from the artist to Robert Delaunay; possibly Paul Guillaume; Ambroise Vollard; sold in 1925 to Juliana Force and returned to Vollard the same year; Galerie Étienne Bignou; sold in 1928 to Chester Dale in New York; bequeathed to the National Gallery in 1963. Shown at Wildenstein in New York in 1928 and in Henri Rousseau: Jungles in Paris at Tate Modern, the Grand Palais and the National Gallery in 2005–06.
What we measured
We profiled five columns and rows at each edge of a 2400 px rendition: means 85–94 left, 83–93 right, 103–117 top, 82–83 bottom, spreads 36 to 214. Painted surface on every edge. Nothing trimmed. Ratio 25646 / 23548 = 1.08917 against the catalogued 140.6 / 129.5 = 1.08571 — 0.32 %.
The National Gallery caps single-request IIIF delivery at 4096 px on the long side, so the file was fetched as regions and reassembled in the browser — nine tiles for the small sheet, sixteen for the large, with tile boundaries computed from the destination pixels so the seams land on whole pixels.
At 300 dpi this file would carry a print 199 cm wide. The paper is the limit here by a very wide margin, which is why your sheet prints at over 1000 dpi.
One thing this picture taught us. Our filter for the Green collection originally used a saturation floor of 0.18, and by that measure this painting registered a coloured area of only 0.08 — it would have been rejected as not green enough, which is absurd. Rousseau's greens are muted and greyed. We lowered the floor to 0.06 on 1 September 2026 and re-checked every work already decided. Measured again, this is the greenest sheet in the catalogue: 91 % of its coloured area.
What we are allowed to sell
The original. Rousseau died in 1910; the European term expired in 1981. Painted in 1909 and exhibited well before 1931, so public domain in the US as well.
The digitisation. The National Gallery of Art states that this object's media is free and in the public domain under its Open Access policy — commercial use permitted, no licence, no fee. File taken from the museum's own IIIF endpoint, not from an aggregator.
Our file. The tonal work and the border are ours. We sell you a print of it; we do not sell you the rights to it.
Rights checked 1 September 2026.
Framing this sheet
- 50 × 50 cm
- Image 38.57 × 42.00 cm, 0.30× original. Margins 5.72 cm sides / 3.73 cm top / 4.28 cm bottom
- 70 × 70 cm
- Image 54.00 × 58.80 cm, 0.42× original. Margins 8.00 cm sides / 5.21 cm top / 5.99 cm bottom
- Orientation
- Both sheets are square; the picture inside them is slightly taller than wide
- Frame
- 50 × 50 cm and 70 × 70 cm are stocked square sizes across Europe. Nearest imperial: 20 × 20 in and 28 × 28 in
- Passepartout
- Optional, and least needed on the 70 × 70 with its 8 cm side margins. If you want a mount, go one frame size up rather than cutting into the border
- Glazing
- The picture is almost entirely close-valued greens; anti-reflective glazing keeps the leaves separable from each other under room light
Measure your frame before you order. Frame sizes vary between makers, and some frames have a rebate that swallows several millimetres on each side. We give the exact printed dimensions above so you can check; we cannot take responsibility for a frame that turns out not to fit.
