Identifying Blenko Glass

Hilery,
I need help with identifying Blenko glass.
Can you tell me where to go - what to buy?
Also does one need Blenko 's permission to copy?

Harry,
I don't know if one must have Blenko's permission to copy catalogs?  We certainly sought and received assistance from Blenko when we published all the catalogs on line -  our purpose was NOT to make money but to allow collectors and researchers access to the catalogs.   To be safe - ask  - before you copy.

Where and what to buy?  Is an easier question. 
Leslie Pina's  books   available via   http://www.amazon.com  are the most useful tools and readily available and inexpensive.  You might also check ebay for these books.

To order Blenko Catalogs   -  http://www.vintagecatalogs.com   these are quality reproductions of older Blenko Glass catalogs.  Price is reasonable quality is excellent.  We've suggested this site to hundreds of collectors and no one has been disappointed.

The WVa. Museum of American Glass in Weston  has a large collection of Blenko Catalogs -  one may visit the Museum to view the catalogs or order reproductions on line.

When searching for ID of glass -  I often go to Blenko Archives -  this site, as well as Blenko Museum  belong to Damon C a New York fine arts specialist who sell modern glass. http://www.blenkoarchive.org/

The Blenko Project  www.blenkoproject.org   also has most Blenko Catalogs published for use in  identification of glass. 
Good  Luck with labeling your glass.  Collecting Blenko or any American Glass  is much easier than proper identification.
