Religious Antique B/W Photo 1920’s Confirmation Class Photo Eastern PA 8 x 10 For Sale

This is an antique photograph of a confirmation class from Eastern PA. It is an 8 x 10 photograph. The minister is seated in the center with the confirmation class surrounding him. Probably from the 1920\'s era.
I do not know the church of origin, but I do know it is a Christian church, probably Lutheran. This was with my family photographs and our family was Lutheran. None of these people are members of my family, however.
There are no markings on the back, hence the blank second photograph.
