Description: This vintage definitive postage stamp from the People's Republic of Bulgaria (Н. Р. БЪЛГАРИЯ) belongs to a specialized 1951 industrial economy series meant to honor national manufacturing achievements. The central vignette portrays the iconic "First Bulgarian Steamroller" angled sharply to showcase its massive forward rolling drum and rear wheels beneath an overhead protective canopy. Printed in a single deep teal-green or dark-green ink via precise photogravure, the design features the text "ПЪРВИ БЪЛГАРСКИ ВАЛЯК" (First Bulgarian Roller) split cleanly along the upper left and right inner frame borders. The right side displays the word "ПОЩА" (Post) positioned directly underneath a large, stylized face value numeral 2. The formal country designation "Н. Р. БЪЛГАРИЯ" firmly anchors the bottom frame line. This specific specimen is completely pristine and unused, showing a perfectly clean background matrix paired with highly uniform comb perforations on all sides.
Circa: 1951-1952
