A+ with the humidor, I actually inherited an Italian majolica cigar humidor from my grandfather, dated maybe around 1920, made by Egisto Fantechi that is similar to this one. I would put the insurance value around $500, and market value probably $150 (could be higher depending on where you would sell it).
If you are getting into majolica, you should invest in "Italian Pottery Marks from
Cantagalli to Fornasetti" for Italian pieces- great book, and very nice author.
