Set of 40 unused vintage greeting cards

This is a set of 40 random greeting cards. There are 28 with envelopes and 12 without envelopes. 

None of these have been used. They are made by a variety of greeting card publishers including Hallmark Hit parade, Gibson, A Quaint Shop, etc There are birthday cards. Congratulations! Thinking of you, get well soon, and blank. There is even a pop-up Get well card

Some of the Cards and envelopes are discolored and stained from being in storage but they are all still in good condition. 

I am unsure of the age of these cards but if I had to guess I would say 1960s. I can't guarantee the glue on the envelopes still sticks.
