Emovieposter/Heritage but for advertising/theatre/propaganda posters?

[Roughoutline]

Happy new year APFers!

Film posters have been a gateway drug for me, and now I'm getting into old posters from advertising, theatre, propaganda etc

Are there any websites that have sales/auction history like emovieposter and heritage, but for these types of poster instead?

Emovieposter and Heritage both have non-movie posters from time to time.

There are auctioneers that specialize in advertising/theater/travel posters etc, but most of them do just a few auctions a year and make internet bidding available via general auction websites such as liveauctioneers.com or invaluable.com

So I would recommend just keeping an eye out on those websites (and eBay of course)

And Saleroom.com.

Christies can sometime do something for these posters, but to align to your question, Christies aren't the emp of the ad posters et al.
