The 1976 family reunion was called The Strauss Family Reunion though the invitation didn't mention it.

The original invitation is a little difficult to read online. It looked similar to this:

FAMILY REUNION SUNDAY AUGUST 15, 1976 8:00AM TILL 8:00PM HANK KOWALSKI PLAYING ALL TYPES OF MUSIC DANCING FROM 2:00 PM TILL DUSK AT LYNDBERG PARK DIX HILLS ROAD HUNTINGTON STATION, L.I. 1/4 MILE OFF JERICHO TPKE. * IN CASE OF RAIN, IT WILL BE HELD INDOORS AT THE PARK.

This is one of two photos of the family gathering. There were more people than could fit in the frame. We're looking for the other photo.
