These two are the same back and front. They are held together by a harmonica system made of red paper. They are used with a light bulb, as shown on the cover. Made by E.O. & Co., Sundbyberg in Sweden.
”E.O.” stands for Erik Olsson : (http://www.uta.fi/~mt55908/kustantajia.htm) or

Re E.O.& Co., production of scraps: This Swedish publisher was in production from around 1947 until 1960, when it was sold to the American Williams, but production stopped in 1971. The originals were sold to England and Mamelok Press Ltd, still being in production today.

More information on the production of "non"-scraps is appreciated.

The following lanterns, sold flat, some with a top and a base with a candle holder, are to be assembled. Those without a base or without a top are possibly to be used with a light bulb. Some are the same on all four sides, and others have a different decoration on each side. Usually they are covered on the inside with colored paper; if not I presume it has been damaged, removed or just forgotten. Some have one panel that can be opened to put the candle in.
The largest one is 25,5 cm high, the smallest one 21 cm high, panels from 13cm up to 20cm wide. Some have little panels that can be removed, then used as an advent calendar.

Below is part of a leaflet of the firm Friedrich Herold, Chamerau in Germany, in which amongst others two cardboard lanterns are offered. The firm is still operational today and they have not been able to date the leaflet, but do state it is before 1957 as since then the telephone numbers changed from 3 into 883.

Re Mr. Jens Ingvordsen, curator Den Gamle By, Denmark: In advertisements as early as 1944 there is a similar lantern as in this collection, in a catalogue from a cooperative company with stores all over Denmark.

A St. Martin's lantern, four different sides, showing the St. Martin's story, one panel opens. It was advertised in the 1957 Herold catalog as “Nr. 204 St. Martins-Laterne mit Motiven aus der Martins-Legend DM 1.20” (ref. Tina Peschel).
Total 25cm high and each panel 13cm wide.

In the models in this collection most of the bases are separate from the panels. In this model it is attached on one side to a panel and it has the inserted candle holder. The holes are probably for ventilation.

Four different sides, two with a Santa, one panel opens; total 24cm high and each panel 13,5cm wide.

Top and base pieces are shown, but the base has the candle holder missing.

I have seen an earlier version also with the base attached (see previous one St. Martin's and the Denmark advertisement), assigned to the 1930s, so they have been made during a longer period.

The description on the back of the envelope starts with the custom of the “Mettenlaterne”. Free translation:
“Handcrafting of “Mettenlaterne” in the Christmas season is an old custom, which was particularly maintained in the Erzgebirge and in the Thüringer area. At the time when there were no street lights, carrying of lanterns in the evening was necessary. During the Christmas season one provided the lanterns with appropriate traditional Christian and general Christmas motives, or special lanterns were manufactured from pasteboard or plywood. These lanterns would be carried going to the early service, also called “Finstermette” and held before daybreak. In the catholic and also in the evangelist church this service is held on Christmas eve, usually starting around midnight.”
This envelope contains 8 transparent pictures, to be stuck in the openings, two sets of double cardboard panels to form the lantern, the cardboard base in which a candle clip, now missing, is to be inserted.
Dimensions, when assembled, would be 23,5 cm high and 4 panels, each 14 cm wide.

These would be oil lights, sometimes called fairy lights, Victorian Christmas lights, ... The earliest have rounded bottoms as they were for hanging with a wire on the tree. Later they had flattened bottoms for standing giving their use more possibilities. Later the oil was replaced by candles. Many different versions, colors and patterns have been made, up to the 1920s. A min-point was their weight.

However, in the 1990s reproductions were, and still are, made in India and Mexico. They are difficult to tell from the antique originals, but in Mr. George Johnson's book, volume III, there is a chapter dealing with these lights.
