An attractive unofficial FDC for the 1969 Isaac Brock Issue, on Brock University envelope, sent by surface mail to Guernsey, Channel Islands.
Unitrade does not list covers like this, but it should be worth more than the standard $2 for an Artcraft or Rosecraft cachet because the corner card ties into the issue, and the surface rate to Guernsey would be much less common at this time. Our estimate is $5.
