Smog Helmet Is Snug A Martian-type head gear startles Londoners. A pretty girl demonstrates and tests the new anti-smog device. A plastic bubble that supplies air-conditioning to the wearer. The inventor was thoughtful in the matter of osculation and perhaps a sip-of-soda, and made room for both. Passersby give funny looks to the young woman wearing a clear helmet that completely covers her head. Man lifts it up to give her a kiss. Unusual invention.
