Authenticity of First Release Blue Note ..Pre 1960


I'm just curious as to what year Blue Note started printing the letter R under the letter E in Note on their labels.

I am aware of first release mono and stereo not having the letter R, all later releases including re-issues were marked this way I believe.

Pre. 1960 Blue Note, is there any other indicators other then markings in the wax and no R on the label?

Finally, What does the R actually stand for?

'r'egistered trademark. as the the year the logo became a registered trademark, it probably goes back to the company's formation. As to the inclusion (or absence) of the circled R... i'd have to get back to you.
Hi Jaybo,
Yes I figured that regarding the circled R but wasn't 100% sure.
I have a few original Blue Note Lps with acouple without the circled R.
I did a search over the net only found one reference to this, CannonBall Adderlys Lp Somethin else.

Thanks for your interest.
Early and late 60's stuff has a dark blue label. with the earlier 60's stuff you can see the deepgrooves, and its slightly heavier than the later 60's stuff(which was pressed by liberty)...slightly heavier too. I believe labels without the trademark are just mistakes, with no real indicatation to age. Don't have any, but I'm trying to confirm with a Blue Note nut! Blue note has been licenced and pressed dozens of times since the company was bought out, so it gets pretty crazy, even for a collector. My atlantic stuff by comparion is easy to detect in regard to age....I'll get back with more factoids , once I make contact with mr.blue note.
