This hand tinted engraving from Curtis's Botanical Magazine is my cup of tea!
Have fun eye surfing on the lines.
The first volume's illustrations were mostly by Sydenham Edwards
who drew and engraved the plates himself until 1792.
It is a copperplate engraving.
You can see the plate's impression on the paper all around the edge.
(See the little N0. 2 right below? There is the impression of the corner of the plate.)
