Fish are celebrated in a new issue of commemoratives for American wildlife coming out this Friday.

Five fish common to American waters are featured in a $2.20 commemorative stamp booklet being issued in Seattle during the convention of the National Wildlife Federation, which is observing its 50th anniversary.

The booklet contains two identical panes of horizontal standard-size 22-cent stamps, five per pane, with one or two fish per stamp.

The fish depicted on a pane are, from top to bottom, the muskellunge, the Atlantic cod, the largemouth bass, the bluefin tuna and the catfish.

The stamps were designed by Chuck Ripper, a Huntington, W.Va., wildlife artist. The stamps have been produced by gravure in magenta, cyan, yellow, tone black and line black. There is a five-digit plate number on the tab of the booklet.

Collectors of first-day-of-issue cancellations have a 30-day grace period from the day of issue -- orders must be postmarked no later than April 20 -- and alternative ways of placing orders.

Collectors acquiring the fish booklet at post offices have the options of affixing single stamps, multiples or a full pane on their envelopes, which must be addressed. The first-day covers should be sent to Customer-Affixed Envelopes, Fish Booklet Stamps, Postmaster, Seattle, Wash. 98109-9991. No remittance is required.

Collectors preferring full processing of covers by the Postal Service should send their addressed envelopes to Fish Booklet Stamps, Postmaster, Seattle, Wash. 98109-9992. They will have only full panes of five stamps affixed on their covers. The size of a full pane is roughly 4 1/2 by 1 3/4 inches. The cost is $1.10 per pane. Personal checks are accepted, cash is not welcomed, payment by postage stamps is not accepted.
