" Doesn't apply to Glass does it?
Mary Helen, Thank you for your note,
Forgive me for not using your photo Blogger wouldn't accept it - the photo shown is very similar to your glass. Blenko did make this LONG ago and is currently making it - The older one is most often etched BLENKO on the bottom and I think if you have them side by side one can tell the difference. Take the old and new and see if you can. My parents have both, old and new and we can always tell the difference. The new is very nice - - - but there is a difference. BLENKO GLASS isn't trying to 'fool' you they have the date stamped on the newer ones. Blenko Glass makes every effort to mark any recycled item so that collectors know when an item was made. Many collectors (like me) are grateful when Blenko re makes an item - otherwise we might never own the item. I'm still looking for those water bottles with handles! Thus far - I have not been able to talk Rodney Wade in to having Blenko re-make Water bottles with handles! Perhaps we can do a letter writing campaign? To answer your question Mary Helen, your older tumbler will retain value. The new tumbler also have value, and both will continue to grow in value. This 448 tumbler has been around for a long time, a classic design. hjh Readers - Your thoughts about this? You all have many more years of experience than I. HELP!
