I am grateful to the colleague who shared this image from a recent Facebook Marketplace ad. It’s an issue of The New Idea for women magazine from July 1, 1956 – selling for $10.00.
Interestingly, the RBA website inflation calculator calculates the 1956 6 pence cover price for the magazine to be worth 83 cents today.
Related to this, I know someone who has collected music and motorbike and car magazines since the 1970s. They started selling them on eBay a year ago and sales are excellent, earning between $10 and $75 a magazine, plus shipping.
