FRAMED MEMORIES: When my son was 2 and already showing great promise as a chatterbox, I took him to old Yankee Stadium in its final season so that he could always say he saw a game where Babe Ruth and Mickey Mantle played. I have the tickets and pictures to prove it. But they've been reduced to a stack of tickets and pictures and commemorative patches and credentials and pins that I keep in my office.These memories deserve better. At the top of my wish list would be custom framing that helps collect these mementoes into something sharp, organized and, most of all, presentable. At Soulard Picture Framing (1701 South 11th Street), they offer a variety of shadowbox-style designs to display treasured items. Cost can run from $150 to more than $1,000. A recent shadowbox owner D. J. Waugh did included three World Series tickets, a picture and the front page of the Post-Dispatch. It cost $260 to complete. By Derrick Goold, Cardinals beat writer
