one possible reason for these Ramona bottles to be without a Holmegaard provenance might be ................... Lutken died twenty odd years back I believe, but assume commercially the decanter design remains successful. So Ramona is still made, but since the designer is no longer with us, his name/initials are no longer applied to the pieces??? Pieces reputed to be by a given designer, but lacking the necessary scratched attribution are potentially open to question - when some reasonable value is involved, then the copyists are sometimes known to be near at hand.
