Lamar Opens Digital Billboards to Grandparents’ Day Photos Across US Markets

Lamar invited families to submit Grandparents' Day photos for possible display on digital billboards, turning a national DOOH network into a moderated community publishing platform.

What happened

Lamar Advertising is inviting families to submit Grandparents’ Day photographs for possible display on its digital billboards, [according to Lamar’s campaign page](https://lamar.com/en/ad-campaigns/grandparentsday), turning part of a national DOOH network into a moderated community publishing slot.

The reported specifics:

Families submit photographs through Lamar’s campaign page

Selected images rotate on digital billboards alongside commercial advertising

The programme includes human moderation and daily submission limits

It spans multiple U.S. markets rather than a single city

What the source establishes

The campaign details come from Lamar Advertising’s own campaign page, so the mechanics, moderation rules and market coverage are first-party statements by the operator rather than independent reporting. Billboard Guide’s analysis concerns what the format implies for advertisers; it does not establish submission volumes, the number of faces involved, displaced commercial inventory or any audience result.

What the format suggests

Running public submissions through commercial faces makes moderation an inventory question rather than a marketing one. Every slot given to a submitted photograph is a slot not sold, and every submission needs a human to clear it before it appears at roadside scale. The daily cap reads as a throughput limit on that review step rather than a way to manage demand.

The transferable point is narrower than the idea suggests. Participation mechanics only pay off outdoors when the reveal works for someone who never saw the call for entries — the passer-by has a few seconds and no context, so the board still has to carry a complete thought on its own.

Unanswered questions

Lamar publishes the mechanics but not the media. It does not state:

How many faces carry submissions, and whether they are unsold slots or committed inventory

Whether commercial rates or availability change in participating markets

Submission volumes and the moderation rejection rate

Whether Lamar repeats the format for other calendar moments
