This is an original envelope with a map and booklet as mailed out by the - Minnesota Division Of Publicity for the "Sportland Of 10,000 Lakes". I had to tear open the envelope in order to take these photos, it had never been opened! So they are all in pretty good shape!
The booklet is 6 x 9 inches, 37 pages. A little waviness, and a bottom corner crinkle & crease on the booklet.
The State Parks map is 19 x 24 inches. Has statistics and parks info on the back.
