Blenko Signatures & Labels
Signatures are of very limited use in identifying Blenko; in the Historic Period they were only used for the latter portion of 1958 through to the early part of 1961 and briefly in 1964 for only a few special designs. Therefore fewer than 10% of designs in the Historic Period may be signed.

Some Historic Period Blenko designs were also imitated by others (see Fakes & Similar); forged Blenko signatures have turned up on some of these items so be aware that a signature alone is no longer a guarantee of authenticity.

Similarly, labels are unreliable identifiers not only because they can easily be moved from one item to another, but also because rolls of unused labels are known to be available. It is not unheard of to find Blenko labels on non-Blenko items.

1958 Engraved Signature
engraved Blenko SignatureThe text "Blenko ©" in script, etched by hand using an engraving tool. This signature was used briefly in 1958 and quickly replaced with the sand-blasted signature below both because this was too time consuming and due to breakage.

Unrealistic rumors persist that the company's then Vice President, William Blenko Jr., was exclusively responsible for engraving this signature and personally sat in the factory and signed hundreds, if not thousands of these items. At least three significant variations of the signature have been documented (see images below), suggesting at least three different signers. Purportedly the source of this rumor is William Blenko Jr. Himself from an undocumented verbal interview circa 2000. It is plausible that he confused the 1958 signature with the hand-engraved signing done for promotional purposes at department stores that he was almost exclusively responsible for after his father's death.

1958 to 1961 Sand-Blasted Logo

Sand blasted Blenko logo signatureThe word "Blenko" with the hand profile underneath and to the right, and the copyright symbol "©" above and centered. Designed by Wayne Husted, this signature was made by sand-blasting through a metal template and NOT with acid as is often mistakenly claimed.
In use from late 1958 to early 1961. This signature can be very difficult to see particularly when applied near the pontil and/or done lightly.

1964; Hand Engraved Signature
