So some time back, i got this shirt from my grandma, who went to the USA several times and on one of those trips, she got this shirt about apollo 11, and since she is 70 years old, and the landing only 57, there might be a chance it might be from the year the landing happened

My question is, whether this shirt could actually be a 1969 original, and if so, is it rare to have one of these?
