Fortunately, we don't have an "attraction" THAT ugly! The seller thinks it's 50s, but it's 60s - it mentions lakes that were stocked in 1961 and 1962. On the back, it says, "All roads lead to Hackensack". How do I know? I bought one on eBay a long time ago (Lucette got to me).
Seller's description:
The Hackensack, Minnesota Resort Area, travel brochure, 1950s(?), map, 12-panel fold-out travel brochure advertsing the resorts in the Hackensack area, a clean, firm, unmarked copy.
