Dos en uno - 2 en 1

There are

• black covers with text "DOS EN UNO"
• orange/white covers with big text "2 en 1"

It is possible that the covers where changed while the barcodes stayed the same. For Biagi, Castillo and Mores both layouts were found.

The tango.info album index uses "2 en 1" to identify the collection:

• https://tango.info/?q=2+en+1

For Troilo, Fresedo, Ledesma, Rossi the names of the LPs are missing.
