Первый - эстонский художник Кристиан Тедер (Kristjan Teder, 1901-1960). О нем довольно много в интернете.

Краткая биография: Kristjan Teder was a painter and a gardener. He came from Tartumaa and his father was a school-teacher. He studied in the Pallas 1919 at Konrad Mägi in 1919-1925 and at Ado Vabbe in 1933-34. Between these two Pallas-periods Teder studied in Paris at the Vassili Schuchayev’s Private Academy. His studies there had a strong effect on his work in late 1920s.

Подписывался он весьма разнообразно, в том числе, и той подписью, что у Вас на картине.

Большое спасибо!!!
