This is a color scan of The Aquarium, Neon Tetra issue, Vol. 7 No. 7, originally copyrighted and printed in 1936 by Innes Publishing Co.
Copyright research indicates original copyright was issued in 1936 under the Copyright Act of 1909, offering a 28 year term without renewal. Database searches (copyright.gov) do not indicate a renewal was made in or before 1964, as was required to extend copyright. A secondary search for combined volumes of The Aquarium periodical, presented as a bound book, was performed and located no additional renewals prior to the Copyright Act of 1978. In short, due diligence has been performed and it appears to be safe.
