WILES' WONDERFUL WIRELESS

For months past the slogan ·•Wiles· Won<lt'rful Wireless" has heen arrepte1l by discriminining huyert> as the symbol of quality.

Attracted by the hig display of l11gh grade rJdio parts and receivers, which combine the utmost dTidt\11cy with reasonable cosc, experimenters a ll over the State have afforded us their pa tronage "hich has enabled us to build up a bigger and better business.

Thanks to the support given to us in the post we have now been able to finalize arrangementR for the opening of an All - Wireless Store at 384 Pitt Street (between Liverpool and Goulburn Streets) on July 6th, where a complete range of our well-known accessories wil I be stocked.

111 thanking Lhose whose support has made this progressive step possible we issue n cordial invitation tu call and inspect the stock ot our new store. The same ¼ireless service will be still carried on at our Head Office and Store, 60-62 Goulburn Street.
