From Brussels to Schaerbeek in 1931

This registered cover was sent from Brussels to Shaerbeek on 9 February 1931, more than 10 years after the Red-Cross stamps had been taken out of circulation! The 2F50 total franking was enough for Express mail (as pencilled below "Recommandé), except that, strictly speaking, the Red Cross stamps had no longer any postage value.
See another cover with stamps used after they had officially been removed from circulation.
