This is only pseudo-science at best
(if at all), but here goes...
• I drew the
yellow box on the right from where the black of the image ends to where the black text ends
(this allows us to ignore the offset of the black printing over the red) under the assumption that they were on the same black printing plate, with the further assumption
(I know nothing about this set) that the design layout had the text centered
(and thus centered with regards to the black image).
• Next, I took the same
yellow box and moved it to connect with the 'beginning' of the black image on the left. The end result is there is a decent amount of empty room between the yellow box and the start of the name
"OWER," which there 'shouldn't' be.
Conclusion: If this card indeed had its name centered in the layout/design, then there is a missing letter that preceded
"OWER" which has been lost to time.
