In more RDJ frame news, I came across these 3 images a while back...
It's hard to be 100% sure with the quality of the 3 images, but these black/dark grey frames with lighter grey areas look to me to be
Salvatore Ferragamo SF639S in the black/grey striped 003 (57□16 135) with dark gradient grey lenses...
The images do
(only just) show the silver signature Ferragamo hinges and the script logo, which is only present on the left arm. Thankfully, the images show
both arms for confirmation that they are at least Ferragamo frames...
The rounded curve of the lenses in the top corners of the frame and the curvature on the lower lighter sections of the frame itself seem to match...
The lightest areas of the grey marble sections of the frame are also clearly visible...
I can't seem to find any more than the 3 images for better confirmation, nor can I establish a date when the images were even taken, but I'll hazard a guess due to when he also wore these hi-tops...

...as circa 2013, which is also when the brown Ferragamo SF634S (from p.207 & p.208) made an appearance in Paris.
I spotted a great deal on a $30 pair...

...and bought them to tuck away as highly viable contenders in anticipation of more images emerging. Hopefully, he may wear these SF frames again at some point in the future when he dons grey in his outfits.
