Botswana Official Free Marks Exhibit

This is an exhibit I put together to illustrate the typology i have developed to show the different Official Free Marks that are used in Botswana.

Given that the envelopes tend to be large and the mark are placed in random locations all over the envelopes made this a very difficult exhibit to mount. Rather than putting the enveloped on typical 8.5 x 11 in. pages, I created 36 in. wide pages and put the enveloped behind the sheets windowing to show the marks.

I have been fortunate to win the following awards for this exhibit:

  • a National Silver-Bronze at Novapex 2010 in Halifax NS
  • a National Gold at Novapex 2015 in Halifax NS
  • a Silver at the 2015 Rocky Mountain APS World Series of Philately Stamp Show in Denver CO, where it also won the Women Exhibitors Sterling Achievement Award

The illustrations provided are from the Rocky Mountain Stamp Show version of the exhibit.
