Inline 3d stacked effect font

[phsymon]

Hi All,

Could anyone identify this typeface, or something similar please, commercial or free would be fine. I initially thought it may be Stack by  Les Lawrence (1969) but they are different.

Any help would be great, I just found this image on an old tumblr.

Bump!

Given that it seems to be two colors (gray + black), it’s probably lettering, not a font. 

Since you din’t gave any background information, we also can’t judge anything from the source.
