At the @Typographics book fair, @ksmallgallery has a copy of this Helvetica Plakat poster I posted about before (https://typo.social/@nicksherman/112302721186509980) for $40 and I’m amazed no one has picked it up yet.

@letterformarchive also has a very reasonably priced copy of this Lettergieterij Amsterdam specimen book that somehow hasn’t sold yet:
