Disney Studio - 2 Original page - Donald Duck, Mickey Mouse

2 Large original Art drawings, 1 of Donald Duck and 1 of Mickey Mouse & Minnie; 42 x 31 cm each..
I think these were published as colouring sheets in a colouring book - they are too large to be an illustration, and all lines close and are tight - especially fit as colouring sheet.
I have no clue who drew this - clearly a very good artist, but usually this kind of work was done by the studio.
No clue either what year this was done.

Very good condition, some minor wear - 1 very small rip, under, the Mickey drawing (see picture).
