William (Bill) Robinson, RIP
Last night I received an email from Will Robinson,"It is with sadness that I need to report that Dad passed away September 12. He passed peacefully in his sleep."
Bill was a long time friend and client of mine and he very active as an advanced postal history collector - particularly of Wisconsin. His collection was recently sold by HR Harmer (sale #3061, October 2022). He will be missed by his many friends in philately.
The note from Will continues as follows:"There is a memorial service and visitation scheduled for September 25 at Lyndahl in Green Bay. Meal to follow. If you cannot attend in person there will be a live stream available.
