1849 (July 28): 20c blue Épaulette, good margins all around, tied
to cover to Ruremonde (Roermond) by "24" barred numeral, further
struck with Brussels cds in blue, "N" notation adjacent stamp
denoting adhesive disallowed as its usage contravened the
Belgian-Dutch Postal Convention, manuscript "35" tax mark in black,
red cds arrival backstamp, a fine franking and rare usage, being
only one of two recorded examples of an Épaulette franking being
disallowed on a cross-border cover to Holland prior to the revised
1852 treaty; with 1999 Van der Linden certificate. (COB 2) Note:
Prior to the Belgian-Dutch Postal Convention of April 1, 1852,
pre-payment of cross-border mail by postage stamps was not
permitted; the "35" manuscript marking on this cover thus indicated
the entirety of the amount due from the recipient, without credit
for the 20 c. Belgian adhesive
