My fathers name was George Floyd Jr., from the Minneapolis Minnesota area. He was an honorary member of the (Order of the Guniea Pig), and was aboard the Albemarle AV5 during Operation Crossroads in the Pacific, around 1946-1947, for the Baker Shot. The “Grand Council, Exclusive Order of Guinea Pigs” is a paper given apparently to each service man aboard the ship that day. The order of the guinea pig is outlined with native women, mermaids & water spouts. The center is a drawing of the water mushroom that contains ships, planes etc.
The inscription states:

Grand Council, Exclusive Order of Guinea Pigs

To all loyal brother pigs, Greetings,
Know Ye, that (Name )
having, through an exaggerated sense of patriotism
subjected your body to the rigors attendant to atom bombs,
hundred foot tidal waves, mermaids,vampires, sand fleas,
typhoons, mal-de-mer, canned beer, cannibals, etc.
is by this writing accorded full status as a brother pig
and all brothers are hereby commanded
to give him due recognition as same,
under penalty of being driven from the common trough.

Given under my hand this 25th day of July 1946.

Signed by an attendant and the Capt. USN

The left hand corner contains the ships seal in red, center bottom is the name and picture of the ship.

I also have a copy of the ships paper ” Tender Times” that was printed after the bomb test.
