Virtual Showcase: Error Notes of the World
Friday, 14 August 2026
Online — live stream + gallery
A ninety-minute guided tour through the world's great printing mistakes — inverted overprints, mismatched serials, missing intaglio — presented by the collectors who own them, streamed live with an interactive gallery. Exhibitors can submit up to five pieces for the showcase; attendance is free for registered members.
Ways to take part
- Attend — see rare collections up close, meet fellow collectors, and learn from the TNH team and guest experts.
- Exhibit — showcase your collection for recognition. Not everything is for sale; exhibiting purely for the story is celebrated here.
- Sell on the floor — exhibitors may sell pieces from their showcase directly at the event, combining visibility with commerce.
