Membership Stamps Identification?

Just added these three stamps to my collection and I'd like to get some more information about them. All seem to be membership stamps.

1). Not sure of country or organization.

2). Translates as "Annual Contribution", so I am guessing is a membership stamp for a union, though I don't know what I.D.F.F. is. Also unsure of country. Maybe Germany or Austria? Also unsure of year.

3). Translates as "Membership Fee". FDJ is an acronym for Free German Youth (Freie Deutsche Jugend), which is a organization in East Germany.

Can anyone fill in the gaps or add any additional information?

For no.2 I think the initials IDFF stand for Internationale demokratische Frauenfoderation, equivalent to Women's International Democratic Federation (WIDF) and Federation Democratique Internationale des Femmes (FDIF). If you look at the stamp shown in the Wiki article cited, the globe and dove logo on the USSR stamp resembles the logo on your membership stamp, but with the French initials around the globe.

In my view, these "stamps" are from the Democratic Republic of Germany, also known as "East Germany" (1948-1990).

Cursus is correct. They are "Spendenmarken" from the DDR. As I understand the system, a person contributes to an organization and receives a Spendenmarke in return. Some organizations even provided albums for their "stamps." They have no postal use.

The first one is for "Sportvereinigung Dynamo"
