Hello, browsing the internet today I came across a site I have not read in a while and thought I would mention it to you - if Australia interests you - because it really is very good. Also it motivated me to think it is about time I listed some more Australia in the cddstamps Bidstart Store
The site is
Australian Commonwealth Stamp
Varieties Image Database 1913-2016
You can find it here. I think you will enjoy looking through a few of the pages. Extremely informative and excellent quality images.
As for the stamps shown above. They are SG 505 - 508 and from the 1972 "Famous Australians" (4th series) issue. The issue was only available in 70c or $1.40 booklets and the outer edge of the pane is imperforate. These from the bottom left of the booklet. No significant catalogue value but nice to collect a one of each from the booklet pane to collect a used "pane" if possible. I have many in stock so will be trying over the coming days to get some listed in the Bidstart Store.
As a competition, these four above will be a prize to the first correct answer, with mailing address, sent to cddstamps@gmail.com - How many postally valid stamps were there on a booklet pane?
Enjoy your stamps.. Best wishes....Michael cddstamps.com with nearly 2000 Australia stock already listed in the Store here
