Hi - I have tickets for the Leonardo Da Vinci Exhibition for tonight January 6th for the 7pm - 7:30pm entry time period and for tomorrow Saturday the 7th for both early day and evening . Face value of the tickets is 16 pounds each but the cost is 40 pounds per ticket Easiest way to reach me concerning how to arrange is by phone/text on 0796 408 5360. Happy to meet right nearby the National Gallery just prior to your entry in order to facilitate exchange. Cheers, 0796 408 5360 .
