Blitzkrieg Bop – the US versions

Let's start from the beginning. In april 1976 Sire records released Blitzkrieg Bop in the United States as the debut single from the Ramones. Unfortunately the single never came in a picture sleeve in the US. There are four different versions of the single: 

The "normal" version with Havana Affair on the B-side. Both tracks in stereo. Issued with the green/white ABC Records company sleeve.

A promo version with Blitzkrieg Bop in mono and Havana Affair in stereo and white labels. The black star marks the A-side.

An alternative promo white label-version with Blitzkrieg Bop in mono and stereo.

This one also came in a stock version with ordinary yellow Sire labels. 

I have never seen the promo versions or the mono/stereo-single with stock labels in a company sleeve. I think they came in plain white die-cut sleeves. If anyone have more information about this, please let me know.
