+1 Leon is correct. The blue Lomaxes are a great way to get into early cobalt for little $$, yet make nice additions to a collection.I'd guess it dates to around 1870's. I noticed anything & everything from Lomax Chicago seems pretty common. Even the Cobalt Blue Hutches which might be more common the the Detroit Norris Cobalt Hutch? I'd guestimate $30 but just a guess. LEON.
