Lot of 4 Die-cut Seattle Postcards, Continental, 1970's Space Needle

These 4 postcards of Seattle likely date to the 1970s or possibly early 1980s. Two are of the Space Needle, one features Seattle Center, and the last is of the University of Washington Quadrangle. They are die-cut continental-size postcards (roughly 4 x 6 inches). Publishers and photographers include Ed Cooper, Plastichrome, Mike Roberts, Max Jensen, James Sneddon, and Bernie McNeil. They are unused and have light evidence of handling (tiny dog ear and faint depression on the University postcard for example), but otherwise have held up well.
