Bert started collecting stamps as a teenager, and then sold them to classmates in school and to his teachers. By the time he was 18, he established his first day cover business. Bert “serviced” first day covers by having the appropriate post office cancel his special first day covers with the appropriate cancellation, and then returning the cancelled covers to his customers. One of Bert's customers was fellow stamp collector
Franklin Delano Roosevelt, who was governor of
New York at the time. ==Honors and awards==
