The photo is about 3 7/8 X 9 5/8 and very good.  The card backing has been trimmed, irregularly at about 6 1/2 X 11 1/2.  On the back side, the trimming has removed first names but luckily retained most of the last names and instrument played.  Several names may be lost on the bottom trimming.  It also identifies the location as River Front Park.
