100rs red postal stationery envelope (H&G B12e, Die III) used with added 1894 100rs black & rose 'Liberty Head' issue (SG 144) on reverse tied by two fine strikes of unusual SANTA VERIDIANA (S. PAULO) '=' cds with '5 7' date showing for the 5 March 1897 with AMBULANTE cds on reverse. Addressed to BELGIUM with RIO DE JANEIRO and Belgian arrival cds's also on reverse. A very unusual cancellation.
