GARAGE UNDER THEATRE.
Included in the plans for a new motion picture theatre at Brighton (Eng.) is provision for an under- ground garage.
The theatre will cost £250,000, and the owners expect motor- owners to be, the greater propor tion of patrons...
This machine has been in con- tant sorvices, except for: periodical overhauls, for more than. four and a half years.
Perhaps no factor in modern business is of more importance than assured delivery of the goods.
If you transport by motor van or lorry, your best assurance of deliver- ies on schedule, so far as your tyres are concerned, is to fit Goodyear Pneu- matic Tyres.
They are made strong and active- strong to resist the troubles that im- pair ordinary pneumatic tyre. per formance; active, to sustain scheduled speeds.
Their bodies are thewed and sinewed- with extra-elastic, extra-durable SUPERTWIST Cord, developed and perfected by Goodyear to meet the specific requirements of present-day carriage on pneumatics.
Their tread is the powerful, slipless All-Weather Tread, famous for trac- tion and safety in any going.
For punctual motor transport, fit re- Hlable Goodyear Pneumatic Tyres.
