First issue 1929, Cat Bale: A.3 dummy booklet. Complete intact booklet containing all the booklet panes, including both advertisement and blank perforated panes. However, while the blank perforated 'stamp' pages are intact, some have experienced adhesion to the advertisement panes due to the effects of humidity and age, impacting the booklet's preservation. Catalog value $3000. Very scarce.                                                                                                                         Dummy booklets, produced without actual stamps but with interleaving, served as promotional tools distributed to advertisers, post offices, and other pertinent entities. They are esteemed for their rarity and historical significance, providing valuable insights into advertising and distribution practices of the era. Highly sought after by collectors, these booklets hold a special place in philatelic and postal history circles.
