Set of 10 Rossignol posters on plants with frame

Rare set of 10 pedagogical posters Rossignol on plants, i.e. 20 boards in total as they are duplex. Complete set numbered from 1 (the plant in General) to 18 (the wallflower) plus another Rossignol poster also numbered 17 (the onion) and 18 (germination) which must come from another set. All the posters are rather in good condition, with some small tears on the edge, some stains and pencil strokes (look at the pictures). A poster is more damaged, it lacks an angle, it is the 7/8, the fruits and the disposition of the leaves. The frame is supplied with the lot (use patina). An exceptional lot as it is rare to find all the boards to follow in these educational posters of the years 50. Ideal for a changing décor over the seasons or cravings. Size: 96 "x 81"
