This is a picture of two membership cards.  The first one states:

MEMBERSHIP CARD

This is to certify that

Dorothy O. Smith

has demonstrated that she is fully qualified and has been granted full membership in THE SPANISH ATHLETES of America 

[Dorothy O. Smith is written in cursive in blue ink by hand, probably by Ellsworth M. Clark.  Also there is a handwritten "s" to turn "he" into "she"]

The second membership card states:

MEMBERSHIP CARD

This is to certify that

Ellsworth M. Clark

has demonstrated that he is fully qualified and has been granted full membership in THE SPANISH ATHLETES of America

[Ellsworth M. Clark is written in cursive in blue ink.  It is Ellsworth's own handwriting.]
