Distinctive characteristics of this form:
 In 1858, a series of blue/blue “Telegram Immediate” envelopes was issued with “New South Wales/Electric Telegraph” embossed in a seal on the flap. The main 28 Telegraph Offices had their names - from Adelong to Wentworth and including Sydney - embossed in the inner oval of the seal. Another envelope had no office name embossed on the flap to permit use at other offices.

The flaps in the archival set were also endorsed with the number of envelopes required – these totals ranging from 150,000 (Sydney) to 5,000.

The delivery envelopes shown below form the only recorded set.
