Thanks, I have more:

Fairly basic printing. Could be stickers from a pack/album for children sold at an art gallery shop or elsewhere.

I would call them stickers

I like them. THey're not stamps of course, but attractive little things. What size are they? Like postage stamp sizes?

Yes Ringo.
Different size but postage stamps size, see photo with U.S. stamps:

This topic reminds me of the Metropolitan Museum Of Art Miniatures Albums published in the 1950s and distributed by the Book of the Month Club:

I'll call them "cinderellas".
Attractive; but, very plain design. No information on the issuing entity or on the painting shown. Look as a souvenir for tourists from a museum. But it can't be as the last painting (a Goya one) is for sure on the El Prado (Madrid, Spain) museum, but he others look from elsewhere.

Thanks, not a souvenir, is a small reproduction of paintings that I like, manufactured by me.
I just wanted to know how to name it.
Cinderella's his name.
