As far as inquiries for large paintings are concerned (ie. 2 x 3 meters), please keep in mind that such items require a considerable amount of work, usually anywhere from six months up to one year. Such oversize requests should then be submitted plenty of time ahead with respect to the date you would like your painting to be finished and ready for delivery.
Artistic reproductions painted following the same authentic age-old methods employed by the Old Masters: egg tempera and gold leaves over wooden tablets.
