USPS Forever Stamps Frogs 2019 booklet of 20

Found throughout the western United States, the Pacific tree frog or Pacific chorus frog (Pseudacris regilla, pictured at lower right) grows no larger than two inches in length and may be one of the world’s most widely heard frogs. Nicknamed the “Hollywood frog,” its calls—rib-bit, rib-bit—have been recorded for use as background noise for nighttime scenes in countless television shows and movies, even those set far from the frog’s actual range.

Each booklet has 20 stamps so 1 booklet = 20 stamps
