Set of 4 retro greeting cards ♪(ᴖ◡ᴖ)♪ I believe the birthday cards in images 2-5 are from the 1970s. Image 5 is a pop-up card. Images 6-7 are items purchased at the post office. Images 8-9 are a fun letter set. It's a parody of "Natchan" juice, and it's become "Yatchan" (^◇^;) I haven't checked it by opening the bag m(_ _)m The birthday cards are very old, so they have some yellowing. *Although they are new and unused, please understand that they have been in someone's possession and have been stored before purchasing m(_ _)m *The greeting cards are unused, but I'm not sure if the letter set has been opened or not, so I've marked it as "like new." #ShowaRetro #LetterSet #BirthdayCard #GreetingCard #Vintage #Rare #Collection
