Here are two envelopes from W. Kopsen and Co. Pty Ltd. (Sydney, Australia). Kopsen was the "K" in Kayen. 1 July 1948. 1 September 1955. There were two USA stamps with the envelopes: Cheers Tony
I think it's interesting that the price of postage had doubled between 1948 and 1955. Nice envelopes BTW.
@Nils Stephenson I noticed that as well. Post war economic reajustment: the price of postage being directly regulated by the Government. Cheers Tony
Postage now in Australia is pitiful for standard mail is $1,00 and I have had mail from Sydney- Albury take close to 10 days if you want 1-2 day it is $1.50
That's a bit of a steep increase. If you adjust for the CPI, threepence in 1955 is now worth 44 cents.
