During the time period from 1 -3 October 2020, Guernsey Post issued Post and Go labels commemorating the 2020 Virtual Stampex show. These are identical to the fishing vessel labels that were issued beginning on 12 Feb 2020 except for the “Virtual Autumn Stampex 2020” overprint. The first label shows Castle Breakwater Lighthouse and the second, Sark Lighthouse. As of the date of this post, these labels are still available through the Guernsey Post website.
