I'd like to express my sincere gratitude to the Postcrossing forum for facilitating the acquisition of these radio-themed maxi cards from a kind Postcrosser in Australia. Purchasing them directly would have cost nearly ₹3,000, but through the magic of Postcrossing, I was able to obtain them in a swap for a mere ₹75. Thank you, Yuri, and thank you to the entire Postcrossing community!
Here are the details of the Maximum Cards:
HMV Caprice, 1961
The popular HMV Caprice was a mid-range stereogram in a low-boy unit, released in 1961. It had a four-valve amplifier, AM radio and BSR fully-automatic turntable.
Kriesler Master Multi Sonic, 1966
The 1966 Kriesler Master Multi Sonic was a hi-fidelity, top-of-the-line stereogram, which boasted eight speakers. It included a plug-in microphone, eight-valve amplifier and a Garrard fully-automatic turntable.
AWA B28 Portable, 1963
The 1963 pale-pink AWA B28 was a portable and battery-operated mono record player, an affordable option for the youth market. While not a high-quality item, it included AWA’s revolutionary, locally-produced transistor amplifier. AWA (Amalgamated Wireless Australasia Ltd) was the first manufacturer in Australia to produce a transistor radio. (Australia Post)
