Fred and Amy, early years. Phil and Elise were young parents.
Christmas ~1967: Phil in plaid flannel, Elise in cat-eye glasses, two babies. Fred would have been two, Amy just born or nearly so. The tree behind them is silver tinsel, the kind everyone had then.
A few years later: Fred on the Big Wheel, Amy standing on the back pegs. El Centro suburban street, big trees overhead. This is how siblings work.
