I think they are more personal than silver.

Since they are hard to read-
1979 Hobie Fleet 53, Division 9, The Sandlapper (funny, my Mom used to be editor at The Sandlapper Magazine)

1979 Hobie Fleet 141 Fifth Annual Points Regatta

1981 Hobie Fleet 141 Division 9, Second Annual Pam Walker Memorial

The Artists were Olin Pate and Valerie May in '79 and Olin and Valerie Pate in '82. Look like pen and ink with acrylic for the color.
