Here’s a 1968 home movie showing the first communion of a group of girls and boys.

Begins with a title card saying "Mary's First Holy Communion 5/5/68.”

People are at church.  Altar boys and children walk down sidewalk in front of church. Girls are wearing communion dresses. 

Children walk out of the church and down the sidewalk after the Mass.

Shot of a mother and her daughter in a communion dress, posing with a nun in front of the church.

Mother with her daughter and son are walking down the sidewalk.

The remainder of the clip shows a group of boys in suits, walking in single file down a sidewalk and, eventually, into church.
