Know It Is German But Not Sure What They Are.

These are from my dad's collection. The first image dont know what they are. Those nos placed there have no idea what they represent whether scott or SG#. The 2nd to the last images one are of a stamp placed in a booklet.The words are in German I guess. Dont understand what it is or means. Feed backs and inputs will be much appreciated. Any guide to references will be very helpful too. Thanks.

The above stamp booklet is the yearly gift of the German Post for persons with a standing order for German stamps with the philatelic service. The stamp itself is in celebration of the the 150 years of the penny black in Great Britain and is cancelled with the first day - Oct. 11th, 1990.

Your first scan is 2 registered mail labels and 1 Meter strip / cutout with slogan.

As not many people still read this type of writing, I'll copy and translate it:
Habeo Stühle sind preiswert und formvollendet.
Habeo chairs are good value and in perfect form.
The Habeo probably means Heinrich Braulecht in Hessisch Oldendorf
