Although the 2020 and 2021 conference exhibits were cancelled, due to Covid-19, work continued behind the scenes. Materials and information continued to be gathered. The result was three separate exhibitions: for 2022,  Alan Oversby (aka Mr. Sebastian); for 2023, Albrecht Becker; and for 2024, Ethel and William Granger. Both the Oversby and Grangers' exhibits have separate accompanying catalogs/books.
