COSGB has several projects underway:
The checklist will list all overprint patterns in text form. For example,
this overprint would have the following listing:
| Received for / CHAS MEEKING & Co. / £ | Rev. 1d. | h3e | S3/B1/S1i |
The catalogue will illustrate all overprint patterns. The PDF version will be free; printed versions will also be available.
Each newsletter will examine an aspect of commercial overprints in detail. Articles will include the history and laws relating to overprints, as well as details on companies that used them.
Part of the catalogue and newsletter projects is the scanning of source materials such as stamps and documents.
