National Promotions and Advertising (NPA) DBA Lambda Lambda Sigma, LLC

3434 Overland Ave
Los Angeles, CA  90034

NPA is an Out-of-Home Advertising innovator and has been the WildpostingSM  industry leader for over 30 years. As the original "street level posters" advertising company, NPA began as a small operation in Los Angeles to support local artists and entertainers.  NPA's WildpostingSM medium is now preferred by many leading advertising agencies, films studios, and record labels.  We also work with smaller independent companies, non-profit organizations, and actively support our local community.


NPA obtains permits that allow us to post on vacant lots and construction sites.  We work with developers and property owners by removing graffiti and debris within a 500 foot radius of the location, keeping our city and its neighborhoods clean, safe and beautiful.  NPA's unique medium offers the flexibility to accommodate a wide array of budgets, creative specifications, and target markets. Street level advertising also lends itself to many buzz-worthy campaigns. 


Thanks for checking out NPA, the original street level ads, we look forward to working with you!
