Phillips-Victoire Leveque de Vilmorin Lithograph

I would like some help identifying the origin. There is ample foxing. It is framed in a solid tiger maple frame ( no seams). I hy ave searched extensively and find only prints/reproductions of the original mid 1850's seed company offset lithographic prints. In the reproductions, there is captioning and other inscriptions. On this, as per the photograph, each vegetable is labeled only with a number and there is an indecipherable inscription in the lower left hand mid corner. I cannot find a single reference to an original print, en folio or removed from same. All help is appreciated.
