W519 vs W521
 

I recently purchased this W521 lot at the recent Legendary auction at: W521 Link

However, it looks like this lot is more like a W519, which Legendary also had here: W519 Link

The first picture is from the W521 lot, and the second is from the W519 lot. Are both lots actually W519 Type 1 cards with the W521's having slightly different background colors? (I'm actually okay with the W521's being W519's because the price was reasonable even though I already have a W519 Type 1 Ruth.)

H&S W521 Ruth
 

For comparison, here's the W521 Ruth from a recent Huggins and Scott auction here: Link Note that in this card, the image of Ruth is flipped and different from the above.

Mixed bag. 521 is 519 with the image flipped. Most of the cards shown are 519s. The only reversed image I see there is Frisch. Best way to tell, besides logos, is the shirt front--normal has left side of the shirt front on top at the center, like a dress shirt. Really nice group, BTW.

Both Ruths are from the same set too (W519-2-1), Ive seen them with the red background before. The card is missing the blue. The purple one is the normal print.

Thanks, guys, appreciate the comments.

Looks like the artist used this photo of Ruth for the card image (just for comparison)

Finally, picked up this W521 Ruth to sorta knock a tough one off my want list. However, this one is a red background, and I know maroon ones are still out there.

Does anyone know if this also has a blue background variation?
