Passover Haggadah - Prague, 1850 - Cover from 1860, Bibliographically Unknown

Ya'ari 696. Otzar Ha'Hagadot 947.
In this Haggadah we find something interesting: a green cover was added to the Haggadah, with a title page similar to that of the title page of the Haggadah. On the cover, the place of printing (Prague) was printed in German as well as the name of a different printer and a different year: 1860. We do not know of any Haggadah that was printed there in that year.
It is most likely that the printing house was left with a surplus of Haggadot from 1850 and when it wanted to market the Haggadot several years later, it added a new cover with the relevant year.
20 leaves.
Condition: Good-Fair. Stains, wear and tear to the margins of the leaves. New cloth binding.
