Very rare TEL AVIV double circle date cancel with 3-letter month in date-stamp (Groten #C12, rated E / Sach #B44; with index letter "C" - undocumented) tied to booklet pane (5 of 6 stamps) of 3m Pictorials (on vertically ribbed thick paper, 13.25 x 14.5 perforation) affixed to cover postmarked 3 JUNE 1937 from TEL AVIV to tiny locale DALBY in Denmark; franked 15m per period postage rate for overseas surface mailed letter & tied by 3x full strike of #C12. The use of a booklet pane here is evidenced by the cropped appearance of the perforations on the top-most and bottom-most horizontal perforations - rare as mostly complete.
