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.
What I'm primarily interested in are the Blue Notes of the 767 Lexington Ave address ,in script, on the covers and no Rs on the labels.

Jaybo , I'm quickly finding out the rabbit hole goes deep.
good luck...collecting blue note is a 'life's work' for some. my friend mr blue note(who is digging into these questions), has every blue note mini-lp cd made with maybe a dozen missing. hundereds of lp's as well, but ironically nothing pre 1960.
