Thanks to everyone for their identification and good advice on the ancient DDVP strip. Unfortunately, I can't dispose of the pesticide strip because it isn't mine. The photo was taken of the strip as it hangs in an exhibit in a public gallery of a well-known museum that shall remain nameless(but if you live in Chicago you can probably figure it out). The exhibit contains a headdress which contains feathers and appears to be made of felt, hanging very close to the DDVP strip.
