Brisbane GPO Obliterator Page
Type 11 A continuous roller type, with each impression of 'GPO' letters 5 mm high, separated by 5 unbroken lines or bars 20 mm wide. Mainly used on newspaper wrappers, parcels and Large Chalons (probably for payment of bulk postage). There are also several examples known on 5s Chalons thay may or may not be genuine - perhaps also for payment of bulk postage? It is known with both thinner and thicker lines as well as differently shaped letters, strongly suggesting that more than one implement was in use.
Examples are known used from 20 July 1867 to 26 November 1903 but these dates may be incomplete as very few examples have dates associated with them. Best collected on wrappers or multiples showing the continuous roller impression. Rated common
