Esslinger Parti Quiz cans are found in eleven sets. Nine sets were produced by Esslinger's Inc. Philadelphia, PA., (sets numbered below). The remainder are by Jacob Ruppert, New York. Those produced by Jacob Ruppert are all zip tabs and are re-issues of the last Esslinger's Inc. set.
Cans indicated below are listed here by the top left statement of "fact", beginning at the seam.

Distinguishing marks of the sets are:
(1) Date on the can,
(2) Relative size of ESSLINGER and PARTI QUIZ,
(3) Relative size of PREMIUM and BEER,
(4) The number of faces (labels),
(5) The number of colors

One color cans have one face and no horizontal lines between the facts. Three color cans have two faces and have the can body, the horizontal lines, and the bottom band and oval in different colors, shown here as can color/ line color/ band color. Many of these multi colored cans have the lines and the band and oval in the same color and they are called two color cans. They are shown here as can color/ line color where it is understood that the third color matches the second. On "three color" cans, the can color is always silver.

All cans have eight rows of "facts".

All sets except Set 4, have the letters in "Parti Quiz" slanted. In Set 4 they are straight.

All sets except Set 5, have the facts printed in white. In Set 5 they are printed in silver.

All sets except Set 8, have the stars in white. In Set 8 they are in various colors. It is believed that Set 8 is actually part of Set 7. On the few known varieties it appears that the designer chose to lay-out the stars in alternate colors on the silver background cans.

Colors are: Blue(BL), Bronze(BR), Green(G), Pink(PI), Purple(PU), Red(R), Silver(S), and Orange(O). When necessary to describe the colors in the two and three color cans, the abbreviations shown in upper case letters will be used.

The term "Bronze" is used here for a range of colors from copper to bronze to gold, varying from set to set, but generally consistent within any set. Differences in shading may be attributed to paint variations from four can suppliers. The editor will not add any colors ! Do the best you can with these.

The previous can numbering system has been abandoned. This was meaningless since all cans may not exist in all color combinations, and it made revisions and additions a nightmare. The check-off chart system simply allows for this possibility. At the present time, a can within a given set that has the same facts may have been identified as being made in five or more given colors while others have only been found in one of the eight colors. A serious effort has been made to indicate those can colors known at this time. Known can colors have been identified by an initial representing the can manufacturer; "A" = American Can Co., "C" = Continental Can Co., "R" = Crown, Cork & Seal Co., "N" = National Can Co., "X" = can company unknown. If no color is identified, the listing came from a source that did not specify can color – *Identified in italics on the lists. Identical cans made by different can companies may result in minor color variations, likewise, fade may produce "unknown" color variations.
 
It is certainly possible that undiscovered cans within a given set may appear. These must be identified by the top statement of "fact". If such is the case, please notify the editor and these new cans will be added. Be sure, however, that you place the can in the proper set without guessing. Others rely on this information and it must be accurate.

An effort is currently underway to identify the different can companies (American, Continental, or Crown) that made each individual can, to better understand the many minor variations, and to establish whether, or not the can companies actually made identical or entirely different sets of "facts". Most variations between the sets can be readily explained as "can company" differences. Larry Handy BCCA #947 is working on this project.
